Stomach polyps are rare, occurring in about 1 % of people undergoing upper gastrointestinal endoscopy — a procedure that examines the lining of the stomach.
The three most common types of stomach polyps are:
- Hyperplastic polyps. These stomach polyps account for more than half of all diagnosed stomach polyps and develop into cancer in about 2 percent of cases.
- Fundic gland polyps. These stomach polyps, found in the top portion of the stomach (fundus), don’t become cancerous, except in people with familial adenomatous polyposis (FAP) syndrome.

Dizziness is a term used to describe everything from feeling faint or lightheaded to feeling weak or unsteady. Dizziness that creates the sense that you or your surroundings are spinning or moving is called vertigo.
As a child, spinning until you were dizzy may have been great fun. But otherwise, finding the room spinning isn’t pleasant at all.
Dizziness is one of the most common reasons adults visit their doctors — right up there with back pain and headaches.

Jet lag, also called time zone change syndrome, is a sleep disorder that can affect anyone who quickly travels across multiple time zones. Jet lag is caused by a disruption to your body’s internal clock or circadian rhythms — which tell your body when it’s time to be awake and when it’s time to sleep. The more time zones crossed, the more likely you are to experience jet lag.
Jet lag can cause daytime fatigue, an unwell feeling, difficulty staying alert and gastrointestinal problems. Jet lag is temporary but it can hinder your vacation or business travel. Fortunately, there are steps you can take to help prevent or minimize jet lag.
