High TSH usually signals an underactive thyroid. Knowing the symptoms of high TSH can help you catch hypothyroidism early and start treatment.
Common Physical Symptoms of High TSH
- Fatigue and low energy, even after sleeping

Reproductive and Metabolic Symptoms
High TSH can disrupt menstrual cycles, reduce fertility, and raise cholesterol levels. In older adults, these symptoms are sometimes mistaken for normal aging — which is why routine TSH screening is valuable.
When to Get Tested
If you have two or more of these symptoms, a TSH blood test is a simple, affordable way to check your thyroid function.
Comprehensive Screening Options
If hypothyroidism is suspected, you may also benefit from a comprehensive health screening or a TPO antibody test to check for Hashimoto's thyroiditis.
