Celiac disease is an immune-mediated inflammatory disease of the small intestines. The immune system attacks gluten molecules (food protein that is found mainly in wheat, barley, and rye) and damages the cells of the small intestines. This leads to malabsorption—the condition when small intestines are not able to properly absorb essential nutrients. Celiac disease is treated by complete elimination of gluten from your diet.

NSAIDs (nonsteroidal anti-inflammatory drugs) are one of the most commonly used drug groups in the world. They help to treat acute or chronic pain and fever and decrease inflammation. NSAIDs inhibit enzymes that are responsible for pain and inflammation. As these drugs are used very broadly and frequently, it’s very important to recognize common side effects and contraindications.

A food allergy is caused when the immune system overreacts to food proteins. You can have an allergy to any food. Food allergy has imposed a global socioeconomic burden. Almost 6% of the U.S. population has a food allergy. The latter affects people of all ages, ethnicities, sexes, and socioeconomic strata. Food allergy symptoms may be diverse: from mild eye and nose itching to life-thretening anaphylaxis.

Stroke is the medical term that describes the condition when the brain dies. The cause of stroke is loss of normal blood supply to brain tissue. A stroke is a medical emergency. If you think you or someone around you has signs and symptoms of stroke, call for an ambulance (in the U.S. and Canada, 9-1-1) right away. The main symptoms of stroke are walking and vision disturbances, weakness of the face and arms, and difficulty speaking. There are 2 main types of stroke: ischemic stroke and hemorrhagic stroke. Stroke can cause transient or permanent disabilities.
