Why do I feel dizzy after a meal?

Postprandial hypotension—low blood pressure after eating—is common in older adults. It occurs when blood flow is diverted away from the body, including the heart and brain, and instead gets routed to the stomach and intestines during digestion.

Heat rash: How to spot it and what to do

Lingering heat waves have brought warnings about recognizing and preventing heat-related illnesses. Heat rash, while not dangerous itself, can signal heat exposure that may lead to more serious conditions. Here's how to avoid and treat it.

Leprosy in Florida: How worried should we be?

News coverage of a case of leprosy in central Florida may have made it seem like there is an increased threat the disease would spread. Misconceptions about this disease have persisted for a long time, but the facts are reassuring.

Overcoming resistant hypertension

People are considered to have resistant hypertension if their blood pressure remains at or above 130/80 millimeters of mercury despite taking the highest dosage of at least three different blood pressure medications and following healthy habits. Many times, it helps to explore other factors that could cause blood pressure to rise. These include failure to take medication correctly, white-coat syndrome, sleep apnea, alcohol intake, and use of over-the-counter pain remedies.

Get moving to manage osteoarthritis

An estimated 32 million Americans suffer from osteoarthritis, and although exercise is often difficult and painful, a regular resistance training program can help them stay active, improve their level of function, reduce pain, and perhaps avoid the condition worsening to the point where they need a joint replacement. Consulting with a physical therapist is recommended to find the right program to meet a person's needs, fitness level, and limitations.

Why are you coughing at night?

Several health issues are associated with nighttime coughing. Some of the most common are postnasal drip, gastroesophageal reflux disease (GERD), medication side effects, and heart failure. When a new nighttime cough lasts more than a few weeks, it's important to go to a doctor to rule out dangerous causes, such as heart failure. The doctor can also determine if a drug side effect, postnasal drip, or GERD is causing the cough, and prescribe medications to treat the condition.
