When it comes to weight, it seems to be more of an issue in our later years…especially after our 60’s. Having a negative body image occurs for over half of women in their 60’s. Men are no exception. In a small Canadian study, half of men ages 60-83 said they felt unattractive because of their weight. Body dissatisfaction is associated with a higher risk of depression, poorer sleep and sub-optimal self care. Many people struggle with controlling those extra pounds that tend to deposit themselves around the middle while losing important muscle mass. Visceral fat is the fat that surrounds internal organs and is hidden in your abdominal cavity. What we have learned since the mid-1990’s, is that the fat cell is an endocrine organ, secreting hormones and other molecules that have far-reaching effects on other tissues. There are a host of chemicals that link visceral fat to a wide variety of diseases. This combination can lead to health problems such as high blood pressure and cholesterol, type 2 diabetes, sleep apnea and a decline in physical function. Your weight is one indicator of your health, but it matters where you carry those extra pounds. Here are some things to know about late life weight gain.

Visceral fat makes more of the proteins called cytokines, which triggers low lying inflammation and is a risk factor for heart disease and other chronic conditions.

Aging is an inflammatory process. The uncomfortable fact is that the fat you gained in your 50’s may continue in your 60’s. There is a natural increase in body fat until your 80’s!! While subcutaneous fat produces a higher proportion of beneficial chemicals, visceral fat produces chemicals that are far more harmful. Visceral fat makes more of the proteins called cytokines, which triggers low lying inflammation and is a risk factor for heart disease and other chronic conditions.

There is also a hormonal mechanism that perpetuates middle age weight gain (obesity) through eating high glycemic foods. Foods that have a high glycemic index pack alot of sugar into a small package. High glycemic foods cause a fast rise in blood sugar resulting in insulin release. Highly processed refined carbohydrates are absorbed quickly, increasing insulin levels that can result in rebound hypoglycemia and insulin resistance. These mechanisms increase insulin sensitivity in adipose tissue but create insulin resistance in muscle and brain. Your body continues to make more and more insulin which leads to metabolic dysfunction, inflammation, weight gain, fatty liver and plaque development. Weight gain has been said to be nothing more than your body’s chemical reaction to foods. It comes down to 2 things: hormones and inflammation.

A 2022 meta analysis described the metabolic consequences of partial sleep restriction. Out of 26 randomized clinical trials, 400 adults were studied under controlled laboratory conditions. It concluded that insufficient sleep results in a clinically significant decrease in whole body insulin sensitivity. This condition can lead to obesity and diabetes. This present study was the first to assess the impact of sleep restriction in post-menopausal women. The proportion of adults with chronic insufficient sleep (< 6 hours/night) is around 30%. And 41.5% of adults ages 60 and older are obese according to the Centers of Disease Control and Prevention. So getting enough sleep is important. At least 7 hours is ideal because sleeping less has been shown to elevate the hormone Ghrelin that signals us to eat. So less sleep= more hunger and calories.

We may want to eat as we did in our 20’s and 30’s but our metabolism slows down significantly as we age. Your body requires fewer calories to keep it working (calories needed for our lungs to breath and our heart to pump). Less muscle mass also contributes to this slower metabolism. We lose lean muscle as we age. So just walking those 10,000 steps is not enough. We need to fit in some weight resistance (weight lifting, push-ups, planks, etc) at least twice per week while consuming abut 25 percent of our calories from protein. Aerobic exercise like walking, biking, jogging or swimming are still important, but our muscles need protection and strength. You lose as much as 3% of overall muscle strength every year in your 60’s. Men hold on to more of their muscle power than women.

Menopause and it’s decline in estrogen also contributes to weight gain. By the time a woman is postmenopausal, 15-20% of her body fat is visceral fat, compared to 5-8% when she was premenopausal. Estrogen has direct actions in pancreatic islet beta-cells in regulating insulin secretion, nutrient homeostasis and in promoting fat burning. When estrogen falls during menopause, it is thought to reduce a women’s ability to use fat as an energy source leading to weight gain, high blood pressure and cholesterol, type 2 diabetes and inflammation. Estrogen replacement therapy may increase a woman’s resting metabolic rate.

Another common killer that becomes more common as we age is our risk for cancer. One reason according to the NIH is the decline in the immune system’s ability to detect and correct cell defects. Obesity is linked to at least 13 types of cancer. Some are hormone related. Obesity creates inflammation which disrupts the immune system and causes dysregulation of the endocrine system. Fat cells increase estrogen and other hormone levels that lead to an increase in cancer: breast, endometrial, thyroid and pancreas to name a few. Losing weight can reduce this risk.

Obesity is also a risk factor for autoimmune disease, a problem more common in women and as we age. This is when the immune system starts to attack the body’s own healthy tissues. People with rheumatoid arthritis in particular have premature aging. Researchers have found that their immune age is about 25 years older than their actual age.

Obesity, especially when there’s lots of visceral fat is a risk factor for faster brain aging and Alzheimer’s disease according to Howard Fillit, M.D. cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation. Belly fat can: reduce blood flow to the brain, shrink brain volume (up to 4%- 8%) and reduce cognitive function.

Think about monitoring your weight, BMI (body mass index- an estimate of your body fat based on your height and weight, aarp.org/bmi) and waist measurement as important as monitoring your cholesterol, blood pressure and blood sugar levels. A healthy BMI is 18.5-24.9 and 25-29.9 is considered overweight. A waist measurement (place a tape measure above your hip bones) above 35 inches for women or above 40 inches for men means you are at higher risk for heart disease or type 2 diabetes according to the National Institutes of health (NIH). Also if your waist size is more than half your height, you might be at greater risk.

Our immune systems can be re-set and inflammation significantly reduced with weight loss. Here are some tips:

1. Increase your protein intake..especially in the morning. Eating 25-30 grams of protein with each meal helps maintain muscle mass and reduces fat gain.
2. Choose fresh farm food over processed food. Consider following the MIND diet (a combination of the Mediterranean and DASH -low sodium diet).
3. Move at least 30 minutes/day for cardiovascular fitness and add weight resistance at least twice per week for muscle strength. Exercise is the best thing you can do to prevent Alzheimer’s disease!
4. Cut down on simple carbs, especially sugar. This includes alcohol too which is a toxin to the brain and destroys sleep. Simple carbs also retain fluid.
5. Get some sleep…at least 7 hours. Avoid late night food and alcohol. Stop eating at 7 PM as it stores more body fat since you are not burning it off.
6. Sunlight, especially in the morning even if it is overcast. It helps elevate Cortisol in the morning which you need for energy and resets your circadian rhythm for better sleep at night by increasing melatonin rise in the evening.
7. Social connection is important. Remember that hormones are involved in weight gain and the more we can reduce high levels of cortisol throughout the day, the less insulin gets produced to allow fat to be stored. When you are connecting and having fun, it lowers cortisol and raises serotonin and oxytocin which help us relax, digest better and utilize glucose for energy more efficiently.  Meditate, deep breathing and prayer.
8. Consider getting a food allergy test. Learn to avoid “trigger foods” (foods you are reacting to) so that inflammation and insulin subside and weight loss can begin. Reactive calories will put on weight.
9. Get your thyroid level checked. It’s a major player when it comes to hormone health since it stimulates metabolism.
10. Drink water. It is essential to drink approximately half your body weight in ounces. For every 16 ounces less than your body needs, it will hold onto half a pound! When you are dehydrated, your body has to extract water from your food and holds on to it in your tissues. When you drink enough, the body can let go of the extra water it’s been holding on to, and the numbers on the scale go down.

There are some new advanced heart disease tools…and boy do we need them! There are some heart-health trends that are concerning cardiologists. There is a crisis in terms of a lowered life expectancy for the first time in decades according to cardiologist Sadiya Khan, M.D., assistant professor of medicine and of preventative medicine at the Northwestern University Feinberg School of Medicine in Chicago. The lowered life expectancy is due to several reasons: 1) midlife and younger adults are dying of heart diseases more often- death rates rose 8.5% for adults aged 45-64 between 2010-2020. 2) Fatalities due to heart disease for those over the age of 65 also rose significantly with our older population growing. 3) The COVID pandemic fueled the heart disease resurgence. The side effects of the pandemic’s long-term legacy of weight gain, inactivity and stress raised heart attack deaths by 21% for those 45-64 and 17.9% for people over age 65. The virus itself also plays a direct role in how lingering heart risks have been found a year after COVID infection. COVID could emerge as the #1 risk factor for future heart disease. We know a lot about how our lifestyle habits- diet and exercise-can prevent or increase cardiovascular risk. There are 4 new advanced heart disease tools to know and ask your doctor about.

1. Cleerly- an FDA approved system created by James Min, M.D. for evaluating heart plaque in CCTA (coronary computed tomography angiography) images. The plaque is assigned to a risk stage determining if it is hard stable plaque (good) or soft unstable plaque (not good). Patients can actually view the pictures and see what’s going on inside their own heart. This motivates people to stick with their medications and healthy habits. Cleerly health
2. Intravascular Lithotripsy is a new technique approved by the FDA in 2021 that uses shock waves to break up hard plaque deposits in vessels (similar to what they use to break up kidney stones). Patients can receive a stent after this procedure that are stronger, safer and more flexible. Biodegradable stents are on the horizon.
3. Advanced heart drugs: Sodium glucose transporter 2 (SGLT-2) inhibitors have been on the market to treat diabetes. But they really reduce episodes of heart failure in patients with or without diabetes. Studies have shown it can be used to cut the risk of hospitalization or death from heart failure by 33%. The other drug is PCSK9 for those who cannot tolerate or have not seen enough of a therapeutic effect with statins. It is given by injection q 3 or 6 months and lowers LDL cholesterol by 50-60% and also reduces the odds of a heart attack by 20% more than statins alone.
4. Transcatheter aortic valve replacement (TAVR). Instead of requiring open heart surgery which is deemed too risky for the elderly population (that need it most), the aortic valve can be repaired by implanting a new valve using a catheter that is threaded through the femoral artery. Patients are usually discharged after 1 overnight stay in the hospital.

According to a 2021 report from the American Heart Association, 77.5% of men and 75.4% of women ages 60-79 have some form of cardiovascular disease. Among those of us 80 and older, 90% have it. And by the time women reach their 70’s or 80’s, their risk of heart disease exceeds that of men. I know these statistics sound daunting….but the more we are aware of our own risk factors and have tools to measure our own heart disease, the more we can be proactive in prevention and early treatment.

Healthy eye sight is dependent upon our overall well-being, which is dependent upon our genetic make-up, the foods we eat, our activity level, work environment and exposure to airborne toxins. Aging macular degeneration (AMD) is one of many eye diseases that can be slowed down. Although we can’t avoid aging or genetics which are the main causes of AMD, we can control other risk factors and delay or slow the progression of the disease.

AMD occurs when there is damage to the part of the retina known as the macula- which is the part of the eye that controls sharp central vision. When the macula deteriorates, it causes blurred vision. It may affect the ability to drive, to see faces and to read smaller print, but it rarely causes blindness. AMD

Specific habits have been identified in studies to be damaging to eye health. The main risk factors besides age and genetics is smoking, high blood pressure and a diet high in saturated fats and refined processed foods. So how can we prevent vision loss and keep our eyes and bodies strong? Here are 6 steps in preventing age-related macular degeneration:

1. Stop Smoking! Studies have shown that smokers have a 2-3 times higher risk in the development of AMD than non-smokers. A 2015 study found damage and inflammation to several layers of the macula in smokers. Smoking causes high blood pressure which raises pressure in the blood vessels and raises oxidative stress and free radicals.

2. Eat more leafy greens which are rich in carotenoids that your eyes need, especially lutein and zeaxanthin. These particular carotenoids have been shown to be low in people with macular degeneration. Collards, kale and spinach can be added to soups, salads, or pureeing them in smoothies. These nutrients in foods or supplements have been found to prevent and even improve AMD in many cases. Vitamin C can enhance the absorption of lutein.

3. Weight loss (if needed) helps digestion and lowers inflammation which allows for a healthier microbiome. Avoid the typical Western Diet which is high in saturated fats and high fructose corn syrups, sugars and processed foods.

4. Choose healthy fats such as omega-3 fatty acids. Omega-3’s have the ability to regulate formation of extraneous blood vessels that distort vision. Eating fish is a great way to increase omega-3 in your diet. Some people need supplementation and 2 grams daily with food is a good starting place. Vegetarians can choose algae, hemp or krill as good sources.

5. Zinc is necessary for a healthy macula and is found abundant in meats and seafood. It is also in nuts, grains and legumes but is not in a readily absorbable form. Zinc supplementation may be needed for vegetarians and vegans. A RBC Zinc level can determine deficiencies.

6. Vitamin D3 is easy to measure in a blood test. Low levels are associated with increases in macular degeneration symptoms. Vitamin D has anti-inflammatory and anti-angiogenic benefits, especially where genetic risk is greatest. D3 has an important role in the immune system and aging process of AMD and all diseases.

Choose a positive, healthy lifestyle that includes exercise, daily meditations or walks in nature and a healthy diet. It may prevent or slow down the diseases of aging and improve the quality of your life.

Here’s to a year of hope. We have slowly come out of this pandemic a little dazed and confused but for most of us all the better and knowledgeable about how precious life is. There were astounding new technologies and medical breakthroughs in 2022. Here is Wellcast’s top 10 Health Breakthroughs:

10. “Smart stethoscopes” are stethoscopes that identify heart murmurs before they can be heard. It can detect the slightest of murmurs which is important since 5-10% of people have one form of valvular heart disease or atrial fibrillation.

9. Hearing Aids: Over-the-counter (OTC) versions have arrived. Close to 90% of people with hearing loss have mild to moderate losses which these OTC versions would help. It is best to get a hearing test first. Learn more at aarp.org/hearing.

8. Eye Implants: For those who have age-related macular degeneration (AMD), the leading cause of severe vision loss in those over age 50, you can now opt for an eye implant device instead of monthly eye injections. This is primarily for the more severe type (“wet AMD”).  The implant releases a steady dose of a drug, ranibizumab, to control blood vessel growth.

7. Ceramic teeth: Titanium implants have been the gold standard for dental implants. Ceramic options are worth mentioning because it is an option that is good for people with metal hypersensitivities and it is healthier for your gums. It also doesn’t show gray metal through the gum tissue.

6. Focused Ultrasound for Parkinson’s Patients: Like a magnifying glass concentrating sunlight… focused ultrasound beams of sound waves pinpoints an area deep in the brain, heating up and destroying cells associated with the movement problems of both Parkinson’s disease and essential tremor.  This FDA-approved procedure has helped calm shaking, stiffness and other movement problems that are due to these nervous system disorders.

5. Blood Test that detects early cancers called the Galleri, multi-cancer early detection (MCED) from the health company Grail screens for more than 50 different cancers. It searches a blood sample for tiny scraps of DNA released by cancer cells. There are some questions about false positive test results which could lead to expensive, invasive and anxiety-provoking procedures and treatments. But then, the earlier a cancer is found the better the outcome. Follow-up studies are currently being done.

4. A new drug to treat Lp (a): Lipoprotein (a) is an independent risk factor for atherosclerotic heart disease. A new drug, Olpasiran is a small RNA molecule that interferes with the synthesis of Lp(a) in the liver. This is a major breakthrough because it is so difficult to treat Lp(a) outside of using oral Niacin (which commonly causes flushing so many people cannot tolerate it) and injectable drugs known as PCSK9 inhibitors (ie Repatha) given every 2 weeks.  Olpasiran is a subcutaneous injection given every 12 or 24 weeks. More studies are being done before it comes out to market.

3. Inhaler Sensors that monitor your meds are now available. Nearly 1/3 of older adults miss doses on their inhaler schedule, and 74% use their inhalers improperly. Propeller Health’s FDA-approved sensors use a smartphone app linked to the senses to keep track of your inhaled medications.                                         For more information go to inhaler sensors

2. Next generation of mRNA vaccinology: An effective COVID-19 vaccine was developed, produced, approved and delivered in less than a year!! New mRNA vaccines are being developed to prevent cancers, Zika virus and others. The world needed a new vaccine technology and what better way than a pandemic to get things started.

1. Paxlovid (nirmatrelvir-ritonavir): an oral pill for the treatment of mild-moderate COVID-19. Prior treatments were intravenous medications at hospitals and certain service centers. This pill that could be easily prescribed reduced hospitalization from 50-80%. A real deal breaker in getting people better and avoiding severe complications and disease progression.

Wishing you a very healthy, peaceful and hopeful New Year!

Urinary tract infections (UTI) are among the most prevalent bacterial infections in both inpatient and outpatient facilities. They affect about 150 million people annually. About 1 in 7 women suffers at least one infection per year. About a third of those women develop another UTI 6-12  months after the first infection.  There are many ways to prevent recurring urinary tract infections. The prevalence of bacteriuria (a common  feature in UTI) for those over the age of 60 is significantly higher in women than men. Nearly 20-30% of women with an infection experience recurrence. High risk populations for UTI include pregnancy, elderly, children, people with an indwelling catheter and those with a neurogenic bladder. Frequent sexual intercourse increases recurrence rate of UTI’s. Abstinence when having an infection will improve recovery and urinating immediately after coitus is recommended along with the higher intake of water.

A recurrent UTI is classified as having 2 symptomatic episodes within the last 6 months or if 3 episodes have occurred within the last 12 months. There are many approaches to reducing the recurrence rate of urinary tract infections. Non-antibiotic choices are best because they are easily managed but also because it prevents the development of resistance and the corresponding adverse reactions of antibiotics. Here are 6 ways to prevent urinary tract infections:

1. Drink sufficient fluids: The rule of thumb is to drink 1/2 your body weight in ounces. So if you weight 140 pounds, then you should drink about 70 ounces of water per day. Of course certain diuretics such as caffeine and alcohol, require adjustment of those numbers as well as exercise so that may mean close to 85 ounces/day. If you are prone to re-infection, caffeine and alcohol should be limited since they can irritate the bladder wall and cause dehydration.
2. Cranberries (Vaccinium macrocarpon): originated in New Zealand and is loaded with phytochemical compounds such as proanthocyanidins (PACs), anthocyanin, benzoic acid and ursolic acid. Escherichia coli (E.coli is a primary pathogen in UTI’s) is prevented from adhering from the uroepithelial cells by PACs contained in cranberries in the urinary tract. Even though studies on long-term prevention using cranberry products have been inconsistent, I still recommend them since they are safe (especially in children), easy to use in an extract capsule form or drink, and clinically effective in many of my patients.
3. D-mannose: This is a simple sugar, or monosaccharide  found in many fruits. Small clinical studies suggest that oral D-mannose may reduce UTI recurrence,  when used alone or when in combination with other ingredients (cranberry extract, tara gum and probiotic bacteria 1-2.5 billion live cells of L. planetarum, L paracasei and Strep thermophilus). It also inhibits E. Coli bacteria from binding to the bladder wall. In one study, the intake of 2 gms of D-mannose dissolved in a glass of water every day showed a significant drop of urinary tract infections compared with placebo.
4. Uro-Vaxom is an immune-stumulant agent with bacterial cell wall components from the strains of E.Coli. Uro-Vaxom caps. In 2 meta studies, the recurrence rate was reduced by 39% compared to placebo. There was a significant reduction from treatment time to breakthrough infections. Uro-Vaxom trial
5. Estradiol or Estriol vaginal cream for postmenopausal women. This treatment serves as therapy for vaginal atrophy and reduces both colonization with uropathogens and also balances the vaginal PH to reduce risk of vaginal bacterial infections.
6. Antibiotic therapy should only be used when all other options have failed. When choosing an antibiotic, make sure a urine culture has been done to choose the right antibiotic and avoid resistance. Single dose postcoital antibiotic prevention is a good prevention especially for women in whom a correlation between recurrent UTI’s and sexual intercourse has been suspected.

Why is it that some people have a normal sense of thirst and drink enough water throughout the day and others don’t have the urge to drink at all?

And more importantly…why don’t the elderly feel thirsty?

So what actually allows us to feel thirsty? It comes from either a low volume of fluids in the body or a higher concentration of certain osmolites, such as sodium. Certain receptors (osmoreceptors) situated in the brain are stimulated by an increase in plasma concentration and causes us to fell thirsty. When the body loses water, it is depleted from both the extracellular and intracellular compartments, but it may not be lost equally from each of those spaces. Regardless of whether the depletion is from the intra- or extracellular compartment, our bodies have a range of compensitory mechanisms that respond. These responses involve certain hormones (Vasopressin), stimulation of certain systems in the kidney to conserve water and sympathetic activation that minimizes changes in body fluid volume and composition mechanism of thirst . These mechanisms are amazing, but they don’t restore body fluids to their original state. For that to happen we have to drink! So when the elderly don’t feel thirsty, it’s important to find ways to help them drink.

Thirst is not always a reliable indicator of dehydration or the bodies need for water. Many people, especially the elderly don’t feel thirsty until they’re already dehydrated. There are many causes for lack of thirst sensation:

1. As we age, the amount of fluid volume in our body decreases.
2. The thirst response in older people becomes weaker, so they may not know they need to drink.
3. The elderly have a decrease in kidney function plus they may be on mediations that lead to more fluid loss, such as diuretics. Dehydration can lead to constipation, electrolyte imbalance, kidney problems, headaches and loss of balance.

Other causes for lack of thirst could be that you are dehydrated and just don’t feel thirsty as dehydration progresses. Your body fails to send signals to your throat and mouth to tell you to drink. Certain illnesses can also reduce the thirst reflex. Diabetes, physical exhaustion and mental disorders are a few examples.

We may also forget to drink due to being too busy, stressed and not paying attention. We know that stress, which stimulates adrenaline (in addition to too much coffee!) can decrease our appetite and sensation of thirst. It can become a bad habit and our bodies can sometimes adapt to this habit.

But the importance of hydration cannot be understated. We need adequate fluids to flush toxins, reduce muscle cramps and headaches, help our mood and energy, think clearly, have healthy skin and hair and improve sleep. Sometimes we can be dehydrated and have nausea so we don’t want to drink or eat and can feel agitated, moody, lethargic and confused.

Needless to say…let’s be more conscious of our drinking habits and stay hydrated.

Suggestions: Drink electrolyte fluids such as sports drinks or electrolyte powders that you put in water. Sparkling water, low sugar fruit juices are helpful if you don’t like the taste of water or mixing water with fruit juice. Reduce tea, coffee and alcohol as they have a diuretic effect. Take small sips instead of large amounts of water all at once.
