Type 2 Diabetes - The Effect of High Thyroid-Stimulating Hormones on Small Blood Vessels

The thyroid gland is located in the neck and is responsible for making and releasing particular thyroid hormones. These hormones make it possible to burn energy for movement and heat. The Thyroid-stimulating hormone (TSH) is released by the pituitary gland situated at the base of the brain. It tells the thyroid gland when to make thyroid hormone. When the thyroid gland is sluggish, the pituitary produces more TSH to stimulate the thyroid to produce enough hormone. When elevated TSH is found, the sufferer is treated with thyroid hormones.

In Type 2 diabetes blood vessels are damaged by high sugar levels. One of the organs to suffer from small blood vessel damage are the kidneys which contain a large number of blood vessels used to cleanse the blood. According to a June 2017 report in the Medical Science Monitor, high levels of TSH were linked with diabetic kidney disease in a sample of 860 people who had previously been diagnosed with Type 2 diabetes.

Scientists at the Tianjin Medical University in Tianjin, China, divided the participants into three groups according to their TSH levels. A total of 76 participants were diagnosed with sluggish thyroid glands because their TSH level was abnormally high…

  • diabetic kidney disease was found most frequently among the participants with the highest TSH levels.
  • diabetics with TSH levels of over 4.2 mU/L were most likely to have kidney disease.

Normal TSH levels range from 0.4 to 4.0 mU/L. To protect their kidney function, Type 2 diabetics should discuss with their physician the possibility of checking their TSH levels.

Surprisingly enough, diabetic retinopathy, an eye disease having to do with damaged blood vessels in the back of the eye, was no more common among those Type 2 diabetics with high TSH levels than in those with low TSH levels. The absence of any sign of diabetic retinopathy was not explained, and future research will be needed to clarify this result.

Does TSH affect blood vessels directly? Why some more than others? Or are the kidneys in some way more susceptible to damage than the eyes? Further research is needed to find the answers.

Low levels of thyroid hormone can lead to…

  • being overweight or obese,
  • feeling tired,
  • having dry skin,
  • feeling cold at room temperature, and
  • having frequent menstrual periods.

High levels of thyroid hormone can result in…

  • being underweight,
  • having an abnormally fast pulse,
  • feeling nervous or anxious,
  • diarrhea,
  • feeling too hot at room temperature, and
  • having irregular menstrual periods.
