Tough to swallow

Published December 1, 2021
Losing the ability to properly swallow should not be attributed to older age. If older adults have persistent trouble swallowing, like the sensation something is stuck in their throat, or if it’s painful to swallow, it could be a sign of an underlying problem and should be checked out. Treatment depends on the source of the swallowing problem, but might include medication, lifestyle changes, and in some cases, surgery.

Sore throat soothers

Published December 1, 2021
Most sore throats are caused by non-life-threatening conditions or certain behaviors. But sometimes a sore throat may be an indication of COVID-19. One should call the doctor if experiencing difficulty swallowing, shortness of breath, a high fever, or a cough that produces blood. Ways to relieve sore throat pain include staying hydrated, using over-the-counter painkillers, drinking warm liquids, using cough drops, using a spray or lozenge that contains an oral anesthetic to numb the throat, and treating an underlying condition causing sore throat pain.

What’s new in diabetes drugs

Published December 1, 2021
Two classes of diabetes drugs—GLP-1 receptor agonists and SGLT-2 inhibitors—have received much attention lately.

And when such breakthroughs do happen –– think of penicillin or COVID vaccines –– the whole world benefits from them.


Less may be more when treating urinary tract infections

Published November 1, 2021

Taming the chronic inflammation of psoriasis

Published November 1, 2021
Psoriasis is a chronic inflammatory condition in which the immune system attacks the skin. It causes painful skin lesions and may also lead to psoriatic arthritis, hypertension, diabetes, chronic kidney disease, or coronary artery disease. Psoriasis treatments include topical steroids, gentle exfoliant lotions, emollients that keep the skin hydrated, ultraviolet light (phototherapy), laser therapies, vitamin A (retinoid creams), and medications (for moderate-to-severe psoriasis). People with psoriasis are encouraged to get vaccinated against COVID-19 with an mRNA vaccine (from either Pfizer or Moderna) as soon as possible, if they haven’t already done so.

4 reasons for tingling or numbness in the arms and legs

Published November 1, 2021
There are lots of reasons for numbness or tingling in the limbs. Constant or recurrent symptoms point to a potentially serious cause. One possibility is peripheral neuropathy, which damages nerves throughout the body. Another is peripheral artery disease—a narrowing of the arteries in the limbs that reduces blood flow. Another is nerve compression, which might be caused by sciatica (irritation of the sciatic nerve in the legs) or spinal stenosis (narrowing of the spinal canal). When numbness or tingling persists, one should report the symptoms to a doctor right away.
