Common signs of an underactive thyroid are tiredness, weight gain and feeling depressed. An underactive thyroid can often be successfully treated by taking daily hormone tablets to replace the hormones your thyroid isn't making. There's no way of preventing an underactive thyroid.
Acute or infectious thyroiditis
Symptoms may include pain in the throat, feeling generally unwell, swelling of the thyroid gland and, sometimes, symptoms of an overactive thyroid gland or symptoms of an underactive thyroid gland.
You may feel nervous, moody, weak, or tired. Your hands may shake, your heart may beat fast, or you may have problems breathing. You may be sweaty or have warm, red, itchy skin. You may have more bowel movements than usual.

Hypothyroidism can contribute to high cholesterol. If you have high cholesterol, you should get tested for hypothyroidism. Rarely, severe untreated hypothyroidism may lead to myxedema coma, an extreme form of hypothyroidism in which the body's functions slow to a life-threatening point.
Or they may not know they have hypothyroidism. In this case, the condition can gradually become more severe and potentially cause a range of complications.
When the levels of thyroid hormones become very low, the symptoms get worse and can result in a serious condition called myxedema coma. Myxedema coma is a rare but life-threatening condition. People with hypothyroidism who are in or near a coma should be taken to an emergency department immediately.
Symptoms include dull facial expressions, tiredness, and weight gain. Blood tests can help diagnose this condition. They can measure the amount of thyroid hormone and thyroid-stimulating hormones in your blood. The goal of treatment is to return your levels of thyroid hormone back to normal.
Myxedema coma refers to the state of severe, life-threatening, and decompensated hypothyroidism in which thyroid hormone levels are dangerously low. The diagnosis appears to be more common in elderly women with long-standing preexisting hypothyroidism.
Stage 3: Subclinical Hypothyroidism
In this stage, TSH levels may be slightly elevated on blood tests (3-10 mU/L), and the levels of free T3 and free T4 are going to be normal. The person's thyroid antibodies may be even higher than in stage 2, as increases in TSH can increase the inflammation of the thyroid gland.
The most severe form of hypothyroidism is myxedema, a medical emergency.
[1] A large laboratory data-based study by Ehrenkranz et al. showed that there is a significant circadian variation in the TSH levels with peak levels occurring between midnight and 8 am and nadir levels between 10 am–3 pm and 9–11pm.
More causes of a hypothyroidism flare
You started or stopped a high-fiber diet. Fiber can reduce your absorption of thyroid medication, so fluctuations are common after starting or stopping a high-fiber diet. You're drinking coffee and/or milk close to your medication time.

How Long Does Hashimoto's Flare Up Last? Most patients who experience flare-ups say that their symptoms last about two weeks, although there are cases where the symptoms return for months or even years at a time.
Untreated hypothyroidism can lead to serious complications, including heart disease and nerve damage. In rare cases, it can be fatal. Most people with hypothyroidism have to take thyroid hormone replacement long term. You will need ongoing thyroid level checks to ensure you are on the right dose.
Hypothyroidism affects everyone differently. The type and severity of symptoms vary from person to person. Some people with hypothyroidism find that their symptoms do not greatly inhibit their ability to work. Others may find it difficult to keep up with the demands of the workplace.
General symptoms may include fatigue, sluggishness, slight weight gain, and intolerance of cold temperatures. Skin — Hypothyroidism can decrease sweating. The skin may become dry and thick. The hair may become coarse, eyebrows may become more sparse, and nails may become brittle.
The afternoon crash means your blood sugar has dropped too low for your brain and body to function normally, causing you to become drowsy, mentally foggy, tired, and unmotivated. Unstable blood sugar is notorious for making it difficult to manage an autoimmune disease such as Hashimoto's hypothyroidism.
Hypothyroidism usually isn't linked to eye disease. In severe cases, however, hypothyroidism may cause swelling around the eyes. It also may cause a loss of hair in the outer part of the eyebrows.
While symptoms can vary, there are many reported signs of a Hashimoto's flare-up, including: Fatigue. Cold intolerance. Constipation.
Thyroid crisis (also called thyroid storm) is a sudden worsening of hyperthyroidism symptoms that may occur with infection or stress. Fever, decreased alertness, and abdominal pain may occur. People need to be treated in the hospital.
