Hand tremor, also known as shaky hands, is an involuntary shaking or trembling of the hands.
Shaking or tremors in the hands can be a symptom of various underlying conditions or factors, such as essential tremors, Parkinson’s disease, multiple sclerosis, hyperthyroidism, anxiety, alcohol withdrawal, and others.
Explaining these factors in detail, here are 7 reasons why you have a shaky hands.
1. Anxiety
Anxiety triggers the body’s protective or defensive response. The rise in blood pressure is one of the signs; along with this, the body’s supply of adrenaline rises, which prompts the heartbeat to accelerate and the muscles to shake and shiver.
2. Alcohol withdrawal
Alcohol withdrawal can cause tremors, particularly in the hands, as the body adjusts to the absence of alcohol. This can be a sign of alcohol addiction and may require medical intervention. The shaking can start anytime between six to ten hours after the last alcohol consumption. Drinking excessive amounts of alcohol decreases the functioning of the brain and the energy level of the body. Then, in response to the alcohol’s drowsy effect, the brain boosts the nerve activity to keep the human body in a high state of alertness.
3. Low blood sugar
Low blood sugar, or hypoglycaemia, can cause tremors, particularly in people with diabetes who take insulin or certain diabetes medications. It typically happens when the blood sugar levels drop below 4 millimoles (mmol) per litre. Along with feeling hungry and sweating profusely; shakiness and trembling serve as initial warning signs. Hypoglycemia can even cause a person to go unconscious under extreme circumstances.
4. Hyperthyroidism
Hyperthyroidism is a condition in which the thyroid gland produces too much thyroid hormone. One of the symptoms of hyperthyroidism is hand tremors, which can affect the hands and fingers.
5. Essential tremor
This is a neurological disorder that causes rhythmic shaking of the hands, head, voice, and sometimes other body parts. It is the most common cause of shaky hands, particularly in older adults. Essential tremor can occur at any age but is most common in people age 40 and older. People with essential tremors may sometimes develop other neurological signs and symptoms, such as an unsteady gait (ataxia).
6. Parkinson’s disease
Parkinson’s disease is a progressive neurological disorder that affects movement. One of the early symptoms of Parkinson’s disease is tremors, which usually starts from one hand and can spread to the other hand and other body parts. Tremors from Parkinson’s disease are most prominent when hands are on the sides of the body or resting on the lap.
7. Multiple sclerosis
Multiple sclerosis is a chronic autoimmune disorder that affects the central nervous system. One of the symptoms of multiple sclerosis is tremors, it develops when a muscle involuntarily contracts and then relaxes, shaking a portion of the body. Tremors can have a substantial impact on a person’s ability to move around, eat, and drink. The symptoms vary, depending on the amount of damage and the nerves which are affected. Some people with se
