What happens when your tsh is too low

Hypothyroidism happens when the thyroid gland doesn't make enough thyroid hormone. This condition also is called underactive thyroid. Hypothyroidism may not cause noticeable symptoms in its early stages. Over time, hypothyroidism that isn't treated can lead to other health problems, such as high cholesterol and heart problems.

Blood tests are used to diagnose hypothyroidism. Treatment with thyroid hormone medicine usually is simple, safe and effective once you and your health care provider find the right dosage for you.

Thyroid gland

What happens when your tsh is too low

Thyroid gland

The thyroid gland is located at the base of the neck, just below the Adam's apple.

The symptoms of hypothyroidism depend on the severity of the condition. Problems tend to develop slowly, often over several years.

At first, you may barely notice the symptoms of hypothyroidism, such as fatigue and weight gain. Or you may think they are just part of getting older. But as your metabolism continues to slow, you may develop more-obvious problems.

Hypothyroidism symptoms may include:

  • Tiredness.
  • More sensitivity to cold.
  • Constipation.
  • Dry skin.
  • Weight gain.
  • Puffy face.
  • Hoarse voice.
  • Coarse hair and skin.
  • Muscle weakness.
  • Muscle aches, tenderness and stiffness.
  • Menstrual cycles that are heavier than usual or irregular.
  • Thinning hair.
  • Slowed heart rate, also called bradycardia.
  • Depression.
  • Memory problems.

Hypothyroidism in infants

Anyone can get hypothyroidism, including infants. Most babies born without a thyroid gland or with a gland that doesn't work correctly don't have symptoms right away. But if hypothyroidism isn't diagnosed and treated, symptoms start to appear. They may include:

  • Feeding problems.
  • Poor growth.
  • Poor weight gain.
  • Yellowing of the skin and the whites of the eyes, a condition called jaundice.
  • Constipation.
  • Poor muscle tone.
  • Dry skin.
  • Hoarse crying.
  • Enlarged tongue.
  • A soft swelling or bulge near the belly button, a condition called umbilical hernia.

When hypothyroidism in infants isn't treated, even mild cases can lead to severe physical and mental development problems.

Hypothyroidism in children and teens

In general, children and teens with hypothyroidism have symptoms similar to those in adults. But they also may have:

  • Poor growth that leads to short stature.
  • Delayed development of permanent teeth.
  • Delayed puberty.
  • Poor mental development.

When to see a doctor

See your health care provider if you're feeling tired for no reason or if you have other symptoms of hypothyroidism.

If you're taking thyroid hormone medicine for hypothyroidism, follow your health care provider's advice on how often you need medical appointments. At first, you may need regular appointments to make sure you're receiving the right dose of medicine. Over time, you may need checkups so that your health care provider can monitor your condition and medicine.

What are the dangers of low TSH?

High or low levels of thyroid-stimulating hormone may increase total mortality risk in adults, and low TSH may specifically increase the risks for incident cardiovascular disease, coronary heart disease and stroke, study data show.

What are the symptoms of low TSH?

Low TSH levels indicate hyperthyroidism..
irregular or rapid heartbeat..
muscle weakness..
nervousness or irritability..
difficulty sleeping..
frequent bowel movements or diarrhea..
weight loss..
mood changes..

Can low TSH cause weight gain?

According to Kitahara, if someone has low thyroid function, their TSH is high, and the thyroid hormones known as T3 and T4 are low—and weight gain often occurs. If someone has an overactive thyroid, or hyperthyroidism, TSH is usually low, the T3 and T4 are high, and weight loss occurs.

What is the treatment for low TSH?

An underactive thyroid (hypothyroidism) is usually treated by taking daily hormone replacement tablets called levothyroxine. Levothyroxine replaces the thyroxine hormone, which your thyroid does not make enough of. You'll initially have regular blood tests until the correct dose of levothyroxine is reached.
