Loss of control of movements is a more common problem than many believe and it can be very uncomfortable and even worrying. It is often associated with neurological diseases, such as Parkinson’s, but as we will see there are other reasons that can originate it, such as anxiety or a normal so-called physiological tremor.

If you are interested in learning more about this topic in depth, do not hesitate to read the following article by FastlyHealabout the causes and treatment of tremor in the left arm .

Physiological tremor

Some people have an almost imperceptible tremor, especially when they stretch their arm and hand . If you were to place a sheet of paper on your hand, you would notice minimal oscillations.

This type of tremor is usually increased by:

  • Stress.
  • Fatigue.
  • Exercise.

What to do?

It may be important to identify when it occurs and what event it is related to. Identifying this can help you control it, identifying and resolving the causes.

Slow exercises, postures in which you need to practice balance, and mental relaxation techniques can be very helpful in reducing tremors.

Tremor in the arm from medications

Some drugs can increase the personal predisposition to suffer physiological tremors, such is the case of:

  • Broncodilatadores.
  • Antidepressants
  • Caffeine.
  • Antipsychotics
  • Antiparkinsonianos (dopaminérgicos).
  • Valproic acid.
  • Lithium.
  • Alcohol.
  • Heavy metals.
  • Amiodarone
  • Anticonvulsivantes.

What to do?

If the medication has been indicated by a medical professional, it is important that you do not stop taking it without first consulting. You can ask him about the possibility of changing or stopping that medication, but if you do it without that precaution, you can suffer from complications when you stop.

Abstinence syndrome

In the absence of an addictive substance, such as narcotics or alcohol, a series of symptoms may appear , such as:

  • Trembling when maintaining a posture (for example, the left arm outstretched) or when trying to perform a movement.
  • Disorientation.
  • Sweating
  • Headache.
  • Trouble sleeping

What to do?

If you think this may be your problem, it is important that you seek help. Giving up a drug is very difficult and even more so if you are alone or alone in this.

Relaxation techniques and physical exercise can be good allies. Valerian tea can help you relax.


If the blood sugar is lower than normal, it may manifest as a tremor in the left arm when trying to move or hold it out.

You may also feel sweating, confusion, palpitations, dizziness, nervousness, among others.

What to do?

Knowing what is happening is essential. If you suffer from diabetes or insulin resistance , you need to control your blood glucose.

If you have never had problems of this type, but you have symptoms that suggest it, you should approach a medical center to be checked and given an accurate diagnosis.

Eating something sweet should help you feel better in this case, but it is key that you pay attention to what you do, what you eat and how you eat. The unhealthy habits are those that generate diseases, if you really want to improve, the logical thing is to modify them.

Tremor from thyroid problems

Faced with an excess of thyroid hormone, you may notice some trembling in your hands , especially when trying to change position or move one or both arms. It can also be accompanied by other symptoms such as weight loss, nervousness, hair loss, excessive hunger.

What to do?

As in the vast majority of chronic diseases, habits and diet are essential to return to a good state of health.

You can perform specific treatments for tremor with medication such as propanolol, but you should know that if you do not treat the cause directly, you will only be covering a symptom. In the following article, we explain in detail what are the causes, symptoms, and treatment of hyperthyroidism .

Tremor in the left arm due to Parkinson’s

One of the most feared causes of arm tremor is this neurological disease . The Parkinson ‘s occurs at the increasing lack of a neurotransmitter called dopa and secreted in an area of the brain. When this substance is missing, a series of symptoms appear such as loss of smell, slowness in movements, stiffness, loss of balance, among others.

What to do?

Parkinson’s is a chronic disease for which there are treatments that try to replace the dopa that is lost.

It is also important to adopt an active posture regarding lifestyle habits:

  • Keep moving.
  • Try to do challenging activities.
  • Check your diet. Choose what helps improve your health and prefer the natural.
  • Drink water. Avoid alcohol, coffee, and artificial drinks.

Tremor from problems in the cerebellum

It is rare but a disorder in the cerebellum may cause a tremor when trying to move that arm. This could be caused by:

  • Vascular diseases
  • Multiple sclerosis or other degenerative disorder.
  • A lump.

You can also present other symptoms such as: lack of coordination, problems measuring the distance of objects, problems walking.

What to do?

These types of symptoms are usually quite noticeable, so they will lead to the consultation. It is important to be attentive or attentive to their progression and, if possible, go to the professional as soon as possible.

Discovering disorders of this type early can change the behavior that will be taken and the prognosis of the disease.
