A pouch that appears at the top of the tube that carries the food and drinks from the mouth to the stomach (esophagus) and causes difficulty swallowing is called Zenker’s diverticulum. It often occurs when the muscle located at the top of the esophagus (cricopharyngeus muscle) is not able to relax to allow the food […]

A genetic condition that often runs in families, passed from biological parents to their children, and causes cellular function problems is called Zellweger syndrome (ZS). It often causes serious health problems after birth. These include problems with the kidneys, brain, and liver, difficulty feeding, movement issues, and others. Unfortunately, it is not possible to cure […]

An infection caused by a bacterium that leads to diarrhea and abdominal pain is called yersiniosis. This bacterial infection usually affects people when handling raw or eating undercooked pork. One effective way to prevent yersiniosis is to make sure the meat is prepared at a safe internal temperature and wash the hands with soap and […]

A viral infection that is caused by infected mosquitoes is called yellow fever. It often occurs when these mosquitoes bite people.

This is a genetic disorder that negatively affects the bones and teeth. It may also cause muscle weakness, deafness, and other health problems. It is called X-linked hypophosphatemia (XLH), and it happens due to a genetic change (mutation). This mutation causes the body to lose too much bone-strengthening phosphate. Physicians usually treat this condition with […]

A health condition caused by a mutation (change) in the BTK gene is called X-linked agammaglobulinemia (XLA). This is an inherited condition, meaning the abnormal gene is passed from the biological parents to the biological children. When it occurs, a part of the immune system does not develop properly, which causes you to get sick […]

Generally, the name of this condition involves multiple health conditions that negatively affect your […]

A rare genetic condition that causes hypersensitivity to UV (ultraviolet) light, eye disorders, and neurological problems is called xeroderma pigmentosum (XP). It often happens due to a genetic mutation (change) that is inherited from biological parents during pregnancy. Unfortunately, there is no way to cure this condition. That’s why treatment focuses on lessening the symptoms […]

This is a condition in which a harmless yellow bump appears near the eyelid skin. It is called xanthelasma, and it can be soft, chalky, or semi-solid.
