Twitching, also known as fasciculations, is the abnormal firing of a single muscle or a group of muscles. People usually experience twitching in their abdomen, particularly the upper abdomen. If you experience twitching in your muscles, you do not have to worry about it because twitching is usually a normal process.

Many people are unaware of the fact that twitching occurs in the muscles, not in the internal organs. Not only in the abdominal area may a person experience twitching in any muscle of the body. Muscles in the legs, thighs, abdomen, biceps, triceps, and neck are also affected. Abdominal twitching is not alarming at all, even though it is extremely annoying sometimes.

Causes of twitching

Muscle twitching is mostly idiopathic, in other words the cause is unknown. However, there are some other factors that may cause the muscles to twitch.

Daily life causes: Dehydration, overeating, an empty stomach, junk food, strain on your midsection, heavy weight lifting, and overactivity like too much exercise are causes that can be overcome with a slight change in your daily routine.

Psychological causes: You might find it strange, but muscle twitching can also be the result of stress or anxiety. Stress hormones released by the brain have a great impact on the human body including the muscles. These hormones can cause your abdominal muscles to twitch which can be very annoying sometimes. Work on eliminating anxiety or stress and you'll see that twitching will disappear.

Biological causes: Some biological problems are also known to cause muscle twitching. Common causes include electrolyte (potassium, magnesium, calcium, etc) imbalance, constipation, diarrhea, hyperacidity, impaired renal function, improper digestion, and impaired renal (kidney) function.

Severe or serious causes: Motor neuron disease is one of the most serious causes of abnormal muscle twitching. If abdominal muscle twitching is really bothering you, you are advised to pay an immediate visit to a doctor to rule out this serious condition. This will not only save you from complications but will also put your mind at ease.

"Abdominal twitching" or "abdominal wall dystonia": Sometimes, people confuse abdominal muscle fasciculation (twitching) with abdominal wall dystonia. It should be kept in mind that abdominal wall dystonia is characterized by an abnormal muscle tone -- not muscle contraction. This disorder causes persistent muscle contractions along with squirming muscle movements. This is the reason why this disorder is also called "belly dancer dyskinesia".
