The thyroid gland uses iodine to produce thyroid hormones — primarily thyroxine (T4) and triiodothyronine (T3). T4 gets converted into T3 (a more active form) in the blood. Thyroid hormones regulate our metabolic rate and affect weight and energy level. The thyroid also produces calcitonin, which contributes to calcium balance. Thyroid hormone production is regulated by a feedback system involving the pituitary gland (a small gland at the base of the brain).
Some causes of symptoms (triggers) are common to all people with asthma, and some are more individual, especially allergens. There are very big differences between people in how easily and how severely they react. The severity of the symptoms or an attack can differ in the same person at different times, and treatment can also be more or less effective.
A glycated haemoglobin (HbA1c) test accurately assesses how well the blood glucose has been controlled over a period of 2–3 months. For non-diabetic individuals, the normal HbA1c level is usually below 5.5%. In people with diabetes, an HbA1c level below 7.0% indicates good control.
Usually, acne begins at puberty and is gone by the early 20s. In some cases, acne may persist into adulthood. Such types of acne include severe forms that affect the body as well as the face (which afflict males more than females) and acne associated with the menstrual cycle in women.

Ovarian cysts and pregnancy may also cause hormonal changes that lead to acne. Some women get acne when they discontinue birth control pills that have been keeping acne at bay
