The most common of these involve problems with the adrenal glands (hyperaldosteronism), or the arteries supplying the kidneys (renal artery stenosis). People most likely to have secondary hypertension include those with resistant hypertension who use three or more medications to manage their blood pressure, and people who develop hypertension before age 30.

Hospitalization after a ministroke? Not necessarily

Someone who has a transient ischemic attack (TIA, or ministroke) needs prompt testing to look for the underlying cause. A 2022 study shows that people can safely get that evaluation at a specialized outpatient clinic rather than having to be admitted to the hospital. The testing usually includes a heart ultrasound (echocardiogram), cardiac monitoring, and imaging tests. The results guide targeted stroke-prevention treatments, which can reduce the risk of a future stroke by as much as 80%.

What’s the deal with dairy and heart health?

Full-fat dairy products such as yogurt and cheese can be part of a heart-healthy diet. Compared with nonfat or low-fat products, full-fat dairy products tend to be tastier and more filling. But because they contain more calories and saturated fat, it’s best to limit full-fat dairy products to one serving a day and combine them with healthy foods, such as fruit, whole grains, and salads. Cheese is often eaten with less-healthy foods such as refined grains and meat, including pizza, burgers, mac and cheese, and Mexican food.

Many conditions of the gastrointestinal tract are easy to diagnose using standard testing. But some such diseases can impact the GI tract without a clear test finding. Disorders of gut-brain interaction are so called because they involve impaired communication between the gut and brain via the nervous system.
