What is hand tremor? What causes hand tremor?

By | 1 June 2021

Tremor, medically called tremor, is defined as the involuntary and rhythmic movement of a certain part of the body, especially one or more of the limbs. Shivering is often seen as uncontrollable shaking, and this discomfort is mostly due to stress and food consumed. However, it can also be a symptom of a serious illness. Frequent hand tremors can be at a level that prevents the person from doing their daily work. Hand tremor, which is among the movement disorders, can also be caused by daily mood changes, intense stress, physical fatigue, and hypoglycemia, popularly known as low blood sugar. This condition, which is common in all age groups, regardless of gender, is not defined as a health problem unless it occurs for a short time, does not limit the daily activities of the person, and becomes evident. Persistent hand tremor caused by some serious ailments is a condition that should be taken seriously. Hand tremors, which are often associated with Parkinson’s disease, can be caused by many different diseases such as hyperthyroidism, epilepsy, and multiple sclerosis. Therefore, the causes of hand tremors should be well investigated and the underlying disease should be diagnosed and treated. Before answering the question of what causes hand tremor at a young age, which physicians often encounter, it is necessary to understand what hand tremor is.

What is a hand tremor?

Hand tremor is an involuntary and rhythmic muscle movement that almost everyone experiences at some point in their life. This situation is mostly seen due to sudden emotional changes such as excitement, anger, and fear, stress, fatigue, metabolic deficiency, excessive consumption of tea and coffee. The complaint of hand tremor after the current mood change or resting completely disappears. This condition, which is called physiological tremor, is completely normal and is not defined as a symptom of any health problem and can be seen in every healthy person. Essential tremor, another type of hand tremor, is the most common movement disorder. The tremor, which usually starts unilaterally, is seen in the other hand after a while. This discomfort, which is initially only seen with a change in mood, becomes more and more frequent.

In the presence of essential tremors, hand tremors, which disappear when the person is alone or at rest, start again with the person’s social environment or increased tremor anxiety. Unlike physiological tremors, essential tremors can start from the hands and spread to the head, tongue, jaw, voice, trunk, hips, and legs. This type of tremor, which occurs regardless of gender, is more common in people aged 60 and over. However, this situation can also be seen after adolescence or in the middle ages. Hand tremor is especially high while eating, drinking water, and writing and can reach a level that makes the person uncomfortable. Essential tremor, which is mostly thought to be due to genetic transmission, is one of the most common neurological diseases after stroke. Involuntary and rhythmic movement in the hand can also be seen as a symptom of many neurological diseases. “What causes hand tremors?” Another answer to the question is pathological tremor. Pathological tremor can often be caused by a disease in the brain and cerebellum, a genetic disorder, or Parkinson’s disease. “How does hand tremor go?”, which physicians often encounter. The question can be answered as the treatment process differs depending on the causes of hand tremors.

Causes of hand tremor

Although hand tremors due to mood changes such as fear, excitement, and anger are considered normal, hand tremors are seen during rest or when going out to a social environment may be the harbinger of different diseases. The drop in blood sugar is among the causes of hand tremors. Hand tremor that occurs 2 to 3 hours after eating is a common symptom of insulin resistance. In addition to these symptoms, fatigue, dizziness and sleepiness are other common symptoms. This condition, which causes many different ailments, from obesity, hypertension, and atherosclerosis, to atherosclerosis, must be brought under control. Another condition that causes hand tremor is excessive alcohol consumption. Alcoholism, which causes many diseases from heart and circulatory disorders to liver damage, from laryngeal and stomach cancer to pancreatic cancer, is a condition that must be controlled by getting help from health institutions. Metabolic deficiencies are another problem that causes hand tremors. Hand tremors are common, especially in vitamin B12 deficiency. The deficiency of vitamin B12, which has important functions such as DNA synthesis in the body, production of erythrocytes known as red blood cells, and regeneration of nervous tissue, can cause many different health problems as well as a hand tremor. Hand tremors, which are also seen due to the use of some medications, may also occur in the following situations:

  • Parkinson’s: Parkinson’s disease, also known as shaky palsy, is slowly progressive motion sickness. The genetic factor is mostly at the forefront in the early occurrence of this neurological disease, which has a prevalence of 1% in people aged 60 and over. Dopamine produced in regions of the brain called substantial nigra provides communication between brain regions called the striatum, which allows the person to make voluntary movements. Hand tremor is a common symptom in Parkinson’s disease, which occurs due to insufficient dopamine production. Parkinson’s symptoms include slowing of movements, decreased facial expressions, and limitation of movement. Parkinson’s, which is a neurodegenerative disease, is also one of the diseases that respond best to treatment and is seen due to cell loss.
  • Epilepsy: Myoclonus or myoclonus, or in other words, epilepsy, which is characterized by arrhythmic jumping movements with a sudden contraction of muscles and muscle groups, is among the diseases that cause hand tremor. In some cases, this very small movement causes movements that cause the person to drop in their hands or the person to fall to the ground in some cases.
  • Polyneuropathy: Hand tremors can also be seen in the presence of polyneuropathy, which is caused by damage to the nerves known as peripheral nerves that enable the person to make sensory, motor, and autonomic nerve movements. The discomfort, which is seen with many symptoms such as tingling, prickling, numbness, and sensitivity to touch, occurs as a result of many different diseases.
  • Dystonia: Dystonia, which causes involuntary movements in the muscles, is a type of movement disorder. It is characterized by symptoms such as muscle contraction, tremors in the hands and vocal cords, and contractions in the face, arms, and legs. The treatment applied after the diagnosis by the neurologist can be medicated, non-medicated, botox injection, or surgical intervention depending on the type of the disease.

How is hand tremor treated?

The cause of hand tremors varies depending on the underlying disease. For example, if hand tremors are caused by fluctuations in nutrition and mood, handshaking ends after this situation is regulated. Hand tremors due to some diseases can be permanent or temporary. Therefore, treatment is directly linked to the exact treatment of the cause of the tremor.

If you have shaken hands, do not neglect to have your health checks.
