Shaking in elderly populations can occur because of benign issues that resolve on their own, or they can be caused by underlying diseases. Not all older adults experience shaking as they age — but if movement disorders run in your family, there’s a higher chance you will develop trembling as well.
Anxiety, stress, fatigue, low blood sugar or too much caffeine can cause or worsen a tremor. So can many types of drugs. Shakiness may be more intense or occur more often if you or a loved one are taking: Mood stabilizers such as lithium.
Involuntary trembling, shaking, or shivering can be due to a medical condition called essential tremor. Essential tremor is a neurological condition, meaning that it relates to the brain.
Essential tremor is a nervous system (neurological) disorder that causes involuntary and rhythmic shaking. It can affect almost any part of your body, but the trembling occurs most often in your hands — especially when you do simple tasks, such as drinking from a glass or tying shoelaces.
Essential tremor (ET) is a neurological disorder that causes your hands, head, trunk, voice or legs to shake rhythmically. It is often confused with Parkinson’s disease.
If you are sick with nausea, vomiting, diarrhea (dehydration) and fever or weakness, you may see tremors, as well. Sleep deprivation that is severe can cause these symptoms and signs.
Feeling weak or shaky is a common acute symptom of a heart attack in a female. This weakness or shaking may be accompanied by: anxiety. dizziness.
Sometimes, body tremors are due to an underlying neurological condition, such as stroke, Parkinson’s Disease, or multiple sclerosis. However, they may also be a side effect of medications, anxiety, fatigue, or stimulant use. A doctor will work to determine the cause and provide appropriate treatments.
If you suddenly feel weak, shaky, or lightheaded—or if you even faint—you could be experiencing hypoglycemia. A headache that comes on quickly, weakness or tremor in your arms or legs, and a slight trembling of your body are also signs that your blood sugar is too low.

Tremors are not always serious, but in some cases, they may indicate a serious disorder. Most tremors can’t be easily treated, but they’ll often go away on their own. It’s important to note that muscle spasms, muscle twitches, and tremors are not the same thing.
Researchers have looked into how vitamin D can affect the nervous system. Some studies have shown that low levels of Vitamin D have also been linked to the tremors found in Parkinson’s and other motor-related conditions. Low levels of vitamin D could aggravate tremors.
