Poor sleep heightens risk of COPD flare ups

A 2022 study found that people with COPD who reported poor sleep had significantly higher risks of experiencing flare-ups of worsened breathing. Poor sleep may more accurately predict COPD flare-ups than a person's smoking history, researchers said.

Could I have lactose intolerance?

Lactose intolerance can develop at any age, prompting gas, bloating, nausea, or diarrhea after people eat or drink dairy products. Secondary lactose intolerance can happen after the small intestine is jolted by surgery, illness, or injury.

The rundown on diarrhea

Everyone experiences acute (short-term) diarrhea at some time. The unpleasant experience often resolves on its own in a few days, but there are situations that require medical attention. Examples include bloody diarrhea, severe abdominal pain, a high fever, and episodes that continue for a week or longer. A medical consultation can help determine if diarrhea is related to a specific bacterium or parasite, a medication side effect, a food intolerance, or an inflammatory bowel disease.

Screening for cognitive dysfunction

Occasional forgetfulness and memory lapses are often dismissed as a sign of normal aging. But if these episodes become more frequent or problematic, or if they affect daily life, older adults should consult their primary care physician, A doctor can offer an evaluation for mild cognitive impairment. This includes a brief in-office screening test of thinking skills like short-term recall, concentration, attention, ability to juggle multiple tasks, and orientation to time and place.

Sleep added to list of essential healthy heart habits

The American Heart Association added sleep to its list of factors for cardiovascular health. The others are a healthy diet; physical activity; low levels of nicotine exposure; and healthy levels of weight, cholesterol, blood sugar, and blood pressure.

Your guide to taking statins

Statins continue to be a first-line treatment for many people at risk of heart attacks and strokes. They help reduce cholesterol levels, reduce plaque build-up, and protect against plaque rupturing, and fight inflammation. Possible side effects are often mild, if they occur, and go away after a brief period. Otherwise, people can manage them by changing the dosage or switching to another type of statin, per their doctor's direction.

Why do I feel so cold all the time?

Several conditions can cause people to feel cold when others are warm. These include low body weight, skipping meals, feeling fatigued, and having a thyroid condition or a low red blood cell count (anemia).

Research upholds use of supplements to slow macular degeneration

Ten years of data suggest that AREDS2 supplements are associated with a reduced risk of macular degeneration progression without any increase in lung cancer risk, according to a follow-up study published online June 2, 2022, by JAMA Ophthalmology.

New thinking on glaucoma treatment

Some people with newly diagnosed mild to moderate open-angle glaucoma have another option for first-line treatment. Instead of using prescription eye drops initially, they can have a laser procedure called selective laser trabeculoplasty (SLT). SLT uses light pulses to help clean up debris clogging the eye's natural drains. Clogged drains lead to elevated eye pressure that damages the optic nerve. SLT's effects wane after three to five years, at which point it may be necessary to have the procedure again, or to begin using eye drops to treat glaucoma.
