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.

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).

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.

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.

After surgery unrelated to the heart, a diagnosis of atrial fibrillation (afib) may be more common than previously thought. These cases, which may constitute 13% of new afib diagnoses, appear to be undertreated.

A bubble study is a test done in conjunction with an echocardiogram to check for the presence of a tiny opening between the heart's upper chambers called a patent foramen ovale. Such an opening could explain how an unexpected stroke happened.

A yearly influenza vaccine may help lower the risk of serious cardiovascular complications, especially among people who've had a recent heart attack. Pneumonia and shingles vaccines also help reduce heart attack and stroke risks. Early fall is a good time to get back on track with these vaccines. Several different types of flu shots are available; experts advise getting whichever one is most readily available. For those ages 65 and older who have a choice, three vaccines (Fluzone High-Dose Quadrivalent, Flublock Quadrivalent recombinant, and Fluad Quadrivalent adjuvanted) may offer slightly better protection than the regular-dose shot and are the preferred choice.

Hair loss is common in the months after recovering from COVID-19 infection. It can also happen in people with long COVID or because of mental stress from the pandemic. COVID-related hair loss is a form of telogen effluvium, a condition in which normal hair shedding ramps up after intense physical or mental trauma. Hair regrowth usually takes six to 12 months. People can speed and support hair regrowth by avoiding harsh hair habits, checking nutrient levels, and applying minoxidil (Rogaine) to the scalp.

Influenza vaccines that contain higher doses and extra ingredients (adjuvants) to boost their effectiveness can provide better protection than the standard flu vaccine for adults ages 65 and older, according to the CDC, and are recommended for the upcoming flu season.

Existing treatments for a type of eczema called atopic dermatitis include creams and ointments, some containing steroids. An ad for a new injected medication pitches its skin-clearing capability, but that isn't the whole story.
