In GERD, the valve at the top of the stomach (where the stomach and the esophagus connect) does not close tightly enough. This allows the contents of the stomach to move up into the esophagus.
GERD usually causes a feeling of burning, warmth, heat, or pain that often starts in the upper part of your belly, just below your breastbone (sternum). This feeling (called heartburn) may spread in waves upward into your throat, and you may have a sour taste in your mouth. Heartburn is sometimes called indigestion, acid regurgitation, sour stomach, or pyrosis.
Pompe disease is a rare, inherited neuromuscular disorder that causes progressive muscle weakness and loss of muscle tissue.
Pompe disease goes by many different names:
Pompe disease can occur between infancy and adulthood, and affects both men and women equally. Approximately one-third of people with Pompe disease are infants (infantile-onset) while the other two thirds are children or adults (late-onset).
Pompe disease is caused by mutations in a gene that makes an enzyme called acid alpha-glucosidase (GAA). The job of this enzyme is to break down glycogen, a form of sugar stored in muscle cells throughout the body. In people with Pompe disease, this enzyme is either missing or in short supply.
The symptoms and severity of Pompe disease can vary widely from person to person. Symptoms associated with the infantile-onset form may include:
Symptoms associated with the late-onset form may include:
Enzyme replacement therapy (ERT) has the ability to treat the underlying cause of the disease. Though ERT is not a cure, providing the missing enzyme may slow the progression of muscle weakness and improve muscle function.
