Shaking in the hands, especially while holding or lifting something, is often a physiological tremor that can be more noticeable with muscle effort, stress, fatigue, caffeine, or anxiety. It can also be seen with weakness, low vitamin levels, thyroid imbalance, or sometimes nerve-related causes. Your HbA1c (6) and BP (130/90) are slightly on the higher side, but are not a direct cause of hand tremors. There is no single medicine to start without knowing the exact reason. Doctors may evaluate factors like thyroid levels, vitamin B12, blood sugar variation, or neurological causes and suggest treatment only if needed after proper evaluation. Taking medicine without a diagnosis may not help. You can try simple steps first. Reduce caffeine, manage stress, sleep well, and maintain a balanced diet. Regular light exercise can improve muscle control. If the shaking is increasing, happens even at rest, or affects daily work, it is important to consult a doctor for proper assessment and guidance.
