Low Thyroid Function Leads to Cardiac Atrophy With Chamber Dilatation, Impaired Myocardial Blood Flow, Loss of Arterioles, and Severe Systolic Dysfunction | Circulation.
Hypothyroidism (underactive thyroid) is a disease where your thyroid gland does not produce sufficient thyroid hormone. This interferes with your body's metabolism that controls heartbeat and temperature, leading to reduced circulation that causes cold feet.
Can thyroid problems cause low oxygen levels? One role of thyroid hormones is to promote oxygen delivery to tissues. So, if you have low thyroid hormone levels (hypothyroidism), your tissues may have low oxygen levels.
It may also cause muscle weakness or loss of muscle control. See your doctor if you know or suspect you have hypothyroidism and you're having troubling or painful symptoms in your limbs.
Hypothyroidism can result in decreased cardiac output, increased systemic vascular resistance, decreased arterial compliance, and atherosclerosis. Impaired cardiac muscle relaxation, decreased heart rate, and decreased stroke volume contribute to heart failure in hypothyroidism.

In very rare cases, a severe underactive thyroid may lead to a life-threatening condition called myxoedema coma. This is where the thyroid hormone levels become very low, causing symptoms such as confusion, hypothermia and drowsiness. Myxoedema coma requires emergency treatment in hospital.
A blood test measuring your hormone levels is the only accurate way to find out whether there's a problem. The test, called a thyroid function test, looks at levels of thyroid-stimulating hormone (TSH) and thyroxine (T4) in the blood. Doctors may refer to this as "free" T4 (FT4).
Plaque buildup, blood clots or narrowed blood vessels can lead to poor circulation. When obstacles or narrow paths slow down blood flow, it's difficult for your body to send blood to every part of your body in an efficient way. Exercise and healthy food can help.
Yellowing of the soles of the feet: An accumulation of beta-carotene in the outer layer of the skin, including the palms of the hand and soles of the feet, creates a yellow appearance. Changes in the toenails:Too little or too much thyroid hormone can result in abnormalities of both the fingernails and toenails.
A swollen fingertip, curved nail, and thickening skin above a nail are often signs of thyroid disease.
hoarseness or deepening of the voice. muscle aches and weakness. muscle cramps. 'pins and needles' sensation in the hands.
Too much iodine can make hyperthyroidism worse by leading the thyroid gland to produce too much thyroid hormone. A person with hyperthyroidism should avoid eating excessive amounts of iodine-rich foods, such as: iodized salt. fish and shellfish.
Strength training, which may involve lifting weights or performing body weight exercises, such as squats and push-ups, can help you counteract some of the effects of hypothyroidism.
