Overhead reaches become more challenging with age. This is due to reduced range of motion, declining balance, and weak muscles. As a result, simply reaching up for an object can lead to shoulder injuries, neck injuries, or falls. Avoiding these injuries requires extra care when reaching up: estimating if something is too heavy before lifting it, using a step stool to reduce the reach, finding something to hold on to while reaching, and determining in advance where to set down an object.

Generalized itching is common and has many potential causes. Examples include skin changes that occur with age; skin conditions; and many other diseases such as diabetes, thyroid disease, kidney disease, and liver disease. Relief involves treating underlying conditions; using medications that ease itching; bathing with lukewarm rather than hot water; using soap only on the armpits, genitals, feet, and face; and moisturizing immediately after showering or bathing.

There’s no clear-cut answer about whether taking antihistamines for allergies increases dementia risk. Antihistamines have anticholinergic effects, which might increase the risk for dementia by blocking a particular brain neurotransmitter or increasing brain inflammation. But studies on whether there’s any link between antihistamines and dementia have produced conflicting findings. Doctors advise taking the lowest antihistamine dose possible or using another medication for symptom relief.

Doctors are rethinking their recommendations about a supplement used to help slow dry age-related macular degeneration (AMD). They’re advising people to keep taking the pill even when they reach the late stage of the disease. Previously, the supplement—a cocktail of antioxidant nutrients known as the AREDS2 formula—was believed to slow disease progression only in the beginning and intermediate stages of dry AMD. New evidence suggests the supplement might also slow vision loss in late-stage dry AMD.

Having type 2 diabetes doubles a person’s odds of heart disease, and this risk may be present as early as 30 years prior to the diabetes diagnosis, according to a 2024 study. The findings support the long-held observation of the shared underlying causes of diabetes and heart disease. These include factors that contribute to both conditions, especially the tendency to accumulate fat in the middle of the body, known as abdominal obesity. This problem tends to occur in tandem with high blood pressure, unhealthy lipid levels, and elevated blood sugar—a cluster of signs and symptoms called metabolic syndrome.

High levels of Lp(a)—a fatty particle similar to LDL cholesterol—may double or triple a person’s risk of a heart attack. About one in five adults may have elevated levels, which also raises the risk of stroke and aortic stenosis. Unlike LDL, which rises with age and is influenced by diet and exercise, Lp(a) remains largely constant over a person’s lifetime, so a one-time test suffices for screening. Lp(a) testing is becoming more common now that five promising new Lp(a) therapies are in development.

Social media sources may share misleading information about canola, soybean, and other seed oils. But these oils, which consist mostly of unsaturated fat, can be a good source of heart-healthy fat when combined with whole, fresh foods rather than in processed foods like crunchy, salty, or sweet snack foods. Consuming unsaturated fat in place of saturated fat (found mainly in animal-based foods) is linked to a lower risk of heart attack and death from heart disease.

After a heart attack or stent placement, people typically take a combination of aspirin and another antiplatelet drug. After one year, the new standard practice is to stop the aspirin, in contrast to the previous practice of stopping the other drug.
