📅 Medical Review Date: November 20, 2025

Your TSH 3 level of 6.56 is a High TSH 3 level.

A TSH 3 level of 6.56 uIU/mL usually means the thyroid gland is underactive. It suggests hypothyroidism. High levels of TSH can cause fatigue, weight gain, cold intolerance, constipation, dry skin, hair loss, depression, muscle weakness, and slow heartbeat. This can be caused by Hashimoto's thyroiditis, iodine deficiency, pituitary disorders, or certain medications. Further tests are often needed to identify the cause and guide appropriate treatment.

High TSH 3 levels may indicate underlying health problems. The normal range is typically between 0.55 uIU/mL and 4.78 uIU/mL. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal TSH 3 range for men is :0.55 - 4.78 uIU/mL
