Top 7 Genetic Disorders

While diseases are caused by several factors, some are genetic. That is, they have little or nothing to do with an individual’s actions or lifestyle. They are mainly passed from parents to their children and can also come as a result of genetic mutations that can either be triggered by certain environmental exposure or occur randomly.

Genetic diseases are often very difficult to control. Most do not even have a permanent medical solution. While treatments can help relieve the symptoms and even prolong the life of a carrier, there is no guarantee that he or she may fully recover from it.

This mucus can block the livings of the digestive system, respiratory system, and reproductive system, leading to severe infections in the lungs and several other body organs.

Since the mucus can block the intestines, vas deferens, and other organs, most people with cystic fibrosis may have serious issues with digestions and fertility.

Cystic Fibrosis occurs when a child inherits two faulty CFTR genes from his parents (one from the father who is a carrier of the recessive gene and one from the mother).

The signs and symptoms of this disease or genetic disorder include ongoing diarrhea, constipation or too much gas in the intestine as a result of the blockage, frequent coughing that brings up bloody or thick mucus as a result of the blockage of the airways, and inability to produce a child as a result of the cervix or vas deferens being blocked. Other symptoms that can be noticed include very salty sweat, fatigue, decreased blood pressure, etc.
