Varicose veins are a common, treatable condition. They occur when valves inside the veins weaken and allow blood to flow back toward the feet, instead of up to the heart. People may be more prone to develop them if there are others in their family who have them. Lifestyle changes, such as increasing exercise and wearing compression stockings, can help prevent them. While varicose veins used to be treated surgically, today they are commonly addressed using less invasive office procedures. Treating veins early can help to prevent complications, such as skin pigmentation changes, leg swelling, and skin ulcers.

A 2022 study examined the brains of older adults after they died, and found that those who had stayed the most active late in life had higher amounts of synaptic proteins. These proteins improve the connections between the brain’s nerve cells.

A groundbreaking blood test might someday identify cancer in people with unexplained but worrisome symptoms like unexplained weight loss, frequent fatigue, constant nausea, and new pain.

Consuming more than a half tablespoon of olive oil per day may protect people from cardiovascular disease, cancer, and Alzheimer’s disease, according to a 2022 study.

The ear can naturally clean its canal of excess wax. However, for hardened wax, people can do home flushing with over-the-counter earwax remover, hydrogen peroxide, or warm baby oil or mineral oil. They should avoid using cotton swabs.

In 2022, Americans are projected to spend $35.6 billion on dietary supplements, even though there is little, if any, evidence of benefits. Loopholes in guidelines and clever marketing allow companies to promote these products with misleading promises. While some people may need specific supplements to help with deficiencies, for the average healthy person, following a diet with plenty of fruits and vegetables provides all essential vitamins and minerals.

Many habits can contribute to poor brain health, but four areas can have the most influence. They are the four S’s: sitting, socializing, sleep, and stress. Research has found that poor habits in these areas can affect cognitive skills like memory, learning, and problem solving, and are linked to a higher risk of cognitive decline and Alzheimer’s disease. Adopting simple lifestyle changes may help.

Heartburn and gastroesophageal reflux disease are two of the most common digestive-related problems, but they often get confused with each other because they share many of the same traits. While the two conditions are connected, they are quite different. Recognizing the difference can help a person adopt lifestyle changes to manage symptoms and know when to seek other options, like medication and surgery.

When it comes to managing blood pressure, doctors tend to focus on lowering the top (systolic) number, but the bottom (diastolic) number also plays an essential role in heart health. Diastolic pressure is the pressure during the resting phase between heartbeats, and helps coronary vessels supply oxygen to the heart muscle. It’s important to keep both blood pressure numbers low per guidelines, but research suggests the diastolic number should not fall too low.

It’s common to have a cough for weeks after an upper respiratory infection. When a cough lasts six weeks or longer, doctors may order a chest x-ray to check for an underlying lung problem. Chronic coughing also can result from medications, postnasal drip, acid reflux, or asthma.
