Feeling shaky for no apparent reason can result from several potential causes. Common reasons include temporary factors such as anxiety, low blood sugar, caffeine intake, or dehydration. Other possible causes relate to medical conditions like overactive thyroid, medication side effects, or neurological disorders such as essential tremor or Parkinson's disease. Anxiety increases adrenaline, which can stimulate nerves and muscles, causing shaking. Low blood sugar can trigger tremors along with other symptoms like weakness and dizziness. Caffeine acts as a stimulant that may also cause shaking. Some medications and recreational drugs have shaking as a side effect. More serious causes involve neurological or systemic conditions that may require medical evaluation. If shaking is frequent, persistent, or accompanied by other symptoms, consulting a healthcare professional is important for proper diagnosis and treatment.
