It is not uncommon for us to experience occasional hand tremors, especially as we age. Medically, tremors occur when muscles contract involuntarily and cause a part of the body to shake. Of these, hand tremors are the most common type and have many causes, according to the health website Healthline (USA).
Side effects of certain medications can cause hand tremors, especially when performing activities such as writing, holding a glass of water, or threading a needle.
"Tremors are common and generally benign. They are a type of movement disorder characterized by shaking. Other body parts such as the head or voice can also be affected," said Dr. Jason Singh at One Oak Medical Hospital (USA).
However, in some cases, people with hand tremors need to see a doctor as soon as possible. The first case to pay attention to is hand tremors but the cause is unknown. In that case, the patient should go for a check-up because this hand tremors can be a warning sign of a serious underlying disease.
Another example is hand tremors accompanied by muscle stiffness, slow movements, or problems with balance and coordination. These can be signs of thyroid disease, Parkinson's disease, stroke, electrolyte imbalance, or even drinking too much alcohol.
In addition, patients should also see a doctor if the hand tremors become more severe or interfere with daily activities such as eating, writing, or typing. In these cases, a doctor should be seen as soon as possible.
Hypoglycemia or extreme fatigue is also a common cause of hand tremors.
Not all hand tremors are a sign of a serious health problem. Many causes of hand tremors are harmless. For example, stress and anxiety can also cause hand tremors. Some factors, such as side effects of medications and surgery, can cause tremors when performing activities such as writing, pouring water, or threading a needle.
Medications that can cause hand tremors as a side effect include antidepressants and antipsychotics. If you suspect that your hand tremors are a side effect of a medication, talk to your doctor about changing your medication if necessary.
Hypoglycemia or extreme fatigue are also common causes of hand tremors. In some cases, hand tremors are caused by drinking too much caffeine, which overstimulates the nervous system and causes tremors, according to Healthline.
