High levels of T4, also known as thyroxine, can be indicative of an overactive thyroid gland or other health conditions. Common symptoms of elevated T4 levels (hyperthyroidism) may include:

  1. Rapid Heartbeat (Tachycardia):
    • An abnormally fast heartbeat or palpitations.
  2. Unintentional Weight Loss:
    • Significant weight loss without intentional changes in diet or exercise.
  3. Increased Appetite:
    • Greater hunger or an increased desire to eat.
  4. Nervousness and Anxiety:
    • Feeling jittery, anxious, or experiencing nervousness.
  5. Irritability:
    • Being easily irritated or having a short temper.
  6. Difficulty Sleeping (Insomnia):
    • Trouble falling asleep or staying asleep.
  7. Sweating and Heat Intolerance:
    • Excessive sweating, particularly in warm or hot environments.
  8. Tremors or Shaking Hands:
    • Trembling or shakiness, especially in the hands.
  9. Muscle Weakness or Fatigue:
    • Weakness in the muscles or persistent fatigue.
  10. Frequent Bowel Movements:
    • Increased frequency of bowel movements or diarrhea.
  11. Thinning Hair:

In some cases, hyperthyroidism may be caused by conditions like Graves’ disease, thyroid nodules, or thyroiditis.

Treatment may involve medication, radioactive iodine therapy, or, in severe cases, surgical intervention to manage the condition effectively.
