Why does generalised anxiety disorder cause tremor?

Tremor is a common presentation of Generalised Anxiety Disorder. It may be most noticeable in the hands, voice, or legs, particularly during worry, anticipation, conflict, or other stressful moments.

Anxiety can keep the nervous system on alert. This response prepares the body to act: the heart may beat faster, breathing can become quicker, and muscles can stay braced. Small, repeated muscle contractions can feel like internal trembling or visible shaking.

Poor sleep, fatigue, caffeine, nicotine, missed meals, and some medicines can make shakiness more noticeable. Tremor also has causes unrelated to anxiety, so a new or persistent symptom deserves a proper clinical review rather than self-diagnosis.

When shaking begins, try slowing your breathing, relaxing your jaw and shoulders, and sitting somewhere safe until the surge settles. Regular meals, enough fluids, a steady sleep routine, and reducing stimulants may also reduce triggers.

Arrange a GP appointment if anxiety or tremor is affecting work, sleep, relationships, or daily activities. A clinician can discuss talking therapies, self-management approaches, and medicines when appropriate, as well as check for other contributors to tremor.

Seek urgent medical help for sudden shaking with weakness or numbness on one side, trouble speaking, a severe new headache, fainting, chest pain, severe shortness of breath, confusion, or a seizure. These symptoms need prompt assessment regardless of whether you also feel anxious.

Contact a healthcare professional soon if tremor is new, getting worse, occurs at rest, follows a change in medicine, or is accompanied by weight change, sweating, palpitations, or problems with balance.

Tell the clinician when the tremor happens, which body part is involved, whether it appears at rest or during activity, and what seems to worsen or ease it. Bring a list of medicines, supplements, caffeine use, and any family history of shaking.

You could ask whether the pattern fits anxiety, whether any tests or medicine review are needed, and which treatment options could address both the anxiety and the physical symptoms.
