What disease can cause muscle twitching

The phenomenon of muscle twitching is generally divided into two types: physiological factors and pathological factors. Physiological factors are related to excessive use of muscles and often occur after strenuous exercise or labor. As long as they are relieved, the muscles will return to normal. There are many types of diseases related to muscle twitching, and this is something we must pay attention to. So, what diseases can cause muscle twitching? Next, let’s look at diseases.

The twitching of muscles is actually caused by the contraction of a group of muscle cells, which is medically called fasciculations. This type of muscle fascicle tremor can have different sizes and amplitudes. Some small tremors can be felt but not seen, while more obvious tremors can be seen with the naked eye. Muscle twitching is usually benign unless it is accompanied by muscle weakness or atrophy. Most benign muscle twitches have no definite cause. They may occur when you are tired or stressed, and drinking tea or coffee may also aggravate them. This type of palpitations is mostly intermittent, but in a few people it may occur frequently due to physical factors.

Many people have experienced eyelid twitching, which is actually a benign fasciculation.

However, muscle twitching can also be a warning sign of some neuromuscular diseases. If muscle twitching is accompanied by muscle weakness and atrophy, you should see a neurologist as soon as possible. These disorders include lesions of the motor neurons in the spinal cord, peripheral neuropathy, and a few muscle disorders.

These diseases can cause problems in the signal transmission between motor nerve cells and muscles. As a result, the unstable nerves will release some redundant signals, which will cause the muscles to jump. The neurologist must examine the area of ​​muscle weakness, assess the degree of muscle atrophy, and perform nerve conduction and electromyography tests to find the cause. Some diseases can also be treated with medications to reduce muscle twitching.

Muscle twitching is most common on the face and limbs, but can occur in any part of the body. As its name suggests, it has a benign course and will not progress to other serious neurological diseases, but it is very annoying. Muscle twitching can occur in only a small group of local muscles, such as involuntary eyelid twitching, or it can be widespread and involve the limbs or the whole body.

Causes of muscle twitching

1. Cold stimulation

For example, if you exercise in an environment with cold water or cold air, muscle cramps are likely to occur if you do not do enough warm-up exercises.

2. Electrolyte imbalance

Especially in the summer, sweating a lot during exercise can cause electrolyte imbalance in the body and cause muscle cramps.

3. Muscle contraction disorder or injury

If the muscles are not relaxed enough due to continuous contractions that are too fast, spasms may occur. Or if the muscles are repeatedly micro-damaged during exercise, protective tonic contractions may occur.

Differential Diagnosis

Muscle fiber tremors

The continuous and rhythmic contraction and relaxation of muscles at a frequency of 4 to 6 times per second is called muscle tremor, which is a symptom of central nervous system disease. Tremor may start from the distal end of one upper limb, then spread to the ipsilateral lower limb and the contralateral upper limb, and later affect the lips, tongue, mandible and head. Emotional excitement may aggravate the tremor, and it will stop completely during sleep anesthesia.
