A 2022 study found that vitamin D deficiency significantly increases the likelihood of age-related loss of muscle strength, known as dynapenia, a major risk factor for falls.

A 2022 study found that among adults 65 and older who undergo major surgery, nearly one in seven dies within a year. Dementia or frailty greatly increase the odds of postoperative death.

A 2023 study found that the DASH diet, rich in whole grains, lean protein, nuts, low-fat dairy, and fruits and vegetables, may dramatically lower the risk of heart problems in women and Black adults.

Irritable bowel syndrome (IBS) affects up to 45 million Americans, two-thirds of whom are women. IBS is categorized into three types depending on which symptoms dominate: diarrhea, constipation, or a mix of both. Possible contributors include changes in gut bacteria, faulty nerve signals between brain and intestine, pelvic floor problems, and genetics. Newer treatment approaches target pathways involved in symptoms. Doctors are also repurposing older drugs for IBS, including certain antidepressants and the antibiotic rifaximin (Xifaxan).

About 96 million Americans have prediabetes, defined by elevated blood sugar levels that are not high enough to qualify as diabetes. Risk factors include overweight or obesity, family history, and inactivity. People with prediabetes may have more infections and frequent urination or blurry vision after big meals. Lifestyle changes such as maintaining a healthy weight, exercising, eating healthy foods, drinking alcohol moderately, and not smoking may prevent prediabetes from progressing to diabetes.

Migraines, which affect nearly 40 million Americans, are likely vastly underdiagnosed and undertreated. Women are three times more likely to get migraines than men, and hormones appear to be a major trigger. Other triggers include stress, disrupted sleep patterns, hunger or dehydration, certain foods or medications, and bright lights or loud noise. Newer medications are more targeted and pose fewer side effects. They include CGRP (calcitonin gene-related peptide) blockers, more effective nasal sprays, and green light therapy.

Discussing sexually transmitted infections (STIs) at the start of a new relationship can protect both partners’ health. Many STIs don’t cause symptoms. Couples can test for STIs together or separately and share results before becoming intimate.
