Most people with obstructive sleep apnea don't know they have it. An at-home or in-lab sleep study can reveal the condition, which hinders breathing while asleep. A doctor can determine which type of test is best for each patient.

More than two years after COVID-19 reached the US, an outbreak of monkeypox is spreading fast outside of Africa. This virus is not new, and it's likely to be less dangerous than COVID, but it's still important to be aware of its symptoms, spread, treatment, and prevention.

The monkeypox outbreak currently traveling around the globe is the largest ever recorded outside of western and central Africa. Controlling this virus demands preventive measures, and one method that has worked to contain previous disease outbreaks may be effective for monkeypox as well.

Inflammatory bowel disease is commonly diagnosed at a point in life when many people are planning families. People who have been diagnosed with IBD are likely to have questions and concerns regarding fertility, conception, pregnancy, delivery, and breastfeeding.

A recent study suggested a vegan diet is an effective treatment for rheumatoid arthritis, and its lead author also said that people should try changing their eating patterns before turning to medication.

There are several types of "sun allergies," including polymorphous light eruption (PMLE), hives, and photoallergic reactions. Learn about these different reactions to sun exposure, as well as prevention and treatment.

Ticklishness falls into two categories: gargalesis (which produces laughter and squirming) and knismesis (the sensation of a feather brushing over the skin, also known as light-touch tickling). It is not clear why some people are ticklish, but it may be a bonding or protective reaction.

Long-established treatments for essential tremor, such as medication and deep brain stimulation surgery, have been joined by a leading-edge technique called focused ultrasound. This incision-free procedure aims sound waves at a spot deep in the brain responsible for tremors. While scientists study ultrasound's long-term effects, the procedure is currently used to treat shakiness on only one side of the body. Other common causes of tremor include Parkinson's disease, caffeine, alcohol withdrawal, anxiety, and fatigue.
