  • staying active with low-impact sports, such as walking and swimming
  • avoiding sudden jolting movements and rough running surfaces
  • avoiding repetitive movements, when possible
  • maintaining a moderate weight
  • seeking medical attention for chronic conditions such as arthritis

Dehydration Due to Diarrheal Diseases

Overview Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. If you don't replace lost fluids, you will get dehydrated. Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults.

Synonyms of Ataxia with Vitamin E Deficiency AVED Familial Isolated Vitamin E Deficiency Isolated Vitamin E Deficiency General Discussion Ataxia with vitamin E deficiency (AVED) is a rare inherited neurodegenerative disorder characterized by impaired ability to coordinate voluntary movements (ataxia) and disease of the peripheral nervous system (peripheral neuropathy). AVED is a progressive disorder that can affect many different systems of the body (multisystem disorder). Specific symptoms vary from case to case. In addition to neurological symptoms, affected individuals may experience eye abnormalities, disorders affecting the heart muscles (cardiomyopathy), and abnormal curvature of the spine (scoliosis). AVED is extremely similar to a more common disorder known as Friedreich’s ataxia. AVED is inherited as an autosomal recessive trait. Vitamin E deficiency often occurs secondary to disorders that impair the absorption of vitamin E from fat including liver disorders, disorders of fat...
