A continuous glucose monitor (CGM)—a small device placed on the arm or belly that measures blood sugar every few minutes—may help people with diabetes recognize the eating and exercise habits that hinder (or help) them control their blood sugar. CGM readouts, which are displayed on a smartphone or portable monitor, show your blood sugar values, trends, and the percentage of time that your blood sugar is in a ”good control” range. Medicare covers CGMs for people who inject insulin at least three times a day or use an insulin pump to control their blood sugar.

People with atrial fibrillation who develop or face a high risk of serious bleeding from anti-clotting drugs may be candidates for procedures that block or remove a part of the heart where dangerous blood clots form. About 90% of blood clots in the heart form in the left atrial appendage (LAA), a small pouch that protrudes from the top of the heart. Two procedures prevent clots from escaping from the LAA and causing a stroke. One delivers a device that blocks the opening of the LAA; the other removes most of the LAA during heart surgery done for another reason.

A rapid heart rate—tachycardia—is a key feature of postural orthostatic tachycardia syndrome, or POTS, a mysterious condition that involves the nervous system and can cause a constellation of symptoms, including fatigue, shortness of breath, headaches, and brain fog, as well as pain in the chest, extremities, or elsewhere in the body. At least half of all cases of POTS are thought to be triggered by an infection (such as mononucleosis), which then spurs inflammation or an autoimmune response. Treatment includes drinking lots of water, eating lots of salt, and graded exercise training.

Pomegranates are rich in antioxidants that help quell inflammation; the fruit may also help lower LDL and blood pressure.

Over a period of nearly two decades, people who ate at least three daily servings of whole-grain foods showed smaller increases in blood sugar levels, blood pressure, and waist size compared with people who ate only small amounts of whole grains.

People can support family members and friends with heart disease by encouraging them to do cardiac rehabilitation, a 12-week program that teaches the fundamentals of a heart-healthy lifestyle and features supervised exercise training. They can also ask about the person’s health goals and ways to help, rather than becoming frustrated if the person appears to be making poor choices. Finally, acknowledging and sharing emotions, such as fear and worry, may improve communication.

Taking low-dose aspirin may increase bruising and minor bleeding from small cuts. Minor bleeding does not necessarily indicate a greater likelihood of experiencing major bleeding.

Yoga addresses multiple factors that underlie heart disease, including both physical and psychological issues. Yoga can improve strength and fitness, foster better sleep, and encourage slow, deep breathing, which helps lower blood pressure and heart rate. The relaxation aspect of yoga trains the nervous system to be less reactive during times of stress. By cultivating greater mind-body awareness, yoga can help people become more in tune with their bodies and how their daily habits affect how they feel.

It appears that people who eat at least three servings of whole grains per day gain fewer inches around their waist than people who eat less than half a serving per day, according to a study published online July 13, 2021, by The Journal of Nutrition.

Keeping the gut microbiome diverse is good for health and may even be tied to healthier aging. To maintain such diversity, it helps to eat a healthy diet that includes lots of fiber, which gut microbes eat. Also, exercise may be helpful to the gut microbiome, since exercise may change the rate at which material moves through the intestines. Other ways to promote a healthy gut microbiome including getting a dog, which exposes us to more microbes; quitting smoking, which relieves stress on gut microbes; and maybe eating more probiotic-rich foods, which may boost beneficial bacteria in the gut.
