11 Endocrine Disorder Symptoms You Should Not Ignore
11. Numbness, tingling, or new-onset carpal tunnel symptoms

Numbness or tingling in the hands and feet can be an early sign of nerve damage from diabetes or from fluid-related nerve compression seen in hypothyroidism. Carpal tunnel symptoms—numbness and tingling in the thumb through ring finger, worse at night—are frequently reported by people with untreated thyroid disease or long-standing high blood sugar. If these sensations are new or interfere with sleep and daily tasks, it’s worth checking blood sugar levels and thyroid function. Early diagnosis of diabetes or hypothyroidism allows treatments that slow or stop nerve damage. Simple measures like wrist splints, glucose control, and optimizing thyroid medication often reduce symptoms. For persistent or progressive neuropathy, see a specialist who can advise on nerve testing and additional therapies.
