Shaking hands in older adults is a common issue that can be caused by a variety of factors. Sometimes the shaking is mild and does not affect daily life, but other times it can make simple tasks like eating or writing more difficult. The most frequent cause is a condition called essential tremor, which is a neurological disorder that leads to uncontrollable shaking, usually in the hands and arms. This type of tremor often gets worse with age and can run in families. It is not dangerous, but it can be bothersome.
Another well-known cause is Parkinson’s disease. This condition affects the brain and leads to tremors, especially when the hands are at rest. People with Parkinson’s may also experience slow movements, balance problems, and muscle stiffness. The tremor from Parkinson’s is different from essential tremor because it is usually more noticeable when the hands are not moving.
Low blood sugar, also known as hypoglycemia, can also cause shaking. This is especially common in people with diabetes, but it can happen to anyone if they haven’t eaten for a long time or have certain health problems. When blood sugar drops, the body responds with symptoms like shakiness, sweating, and a fast heartbeat. Eating something with sugar, like fruit juice or candy, can help bring blood sugar back to normal.
An overactive thyroid, called hyperthyroidism, is another possible cause. When the thyroid gland produces too much hormone, it speeds up the body’s metabolism. This can lead to hand tremors, weight loss, and a faster heart rate. Sometimes, vitamin deficiencies, especially a lack of vitamin B12, can also cause tremors and other neurological symptoms.
Lifestyle factors play a role too. Drinking too much caffeine, not getting enough sleep, feeling stressed, or using certain medications can all make hand tremors worse. Reducing caffeine, improving sleep habits, and managing stress can help reduce the shaking in many cases.
In some older adults, tremors may be related to other health issues or medications. It’s important to talk to a doctor if shaking hands become a problem, especially if it starts suddenly or gets worse quickly. A healthcare provider can help figure out the cause and recommend the right treatment.
