That means that your thyroid is not working properly. It is not producing enough thyroid hormone, and it is functioning rather slow. You can experience hair loss, weight gain, depression, forgetfulness, lowered mental cognition(difficulty in problem solving) high blood pressure, irregular heart beat, low metabolism, and the list goes on. Your thyroid is an adrenal gland located in your neck. It is usually affected in cases of an autoimmune disease such as Hashimoto's disease, and can become quite serious. It affects men and women both; but is more likely to develope in women. It is one of the hardest adrenal, autoimmune diseases to detect, and can often be misdiagnosed. Many people can have it and not know it for years. It is actually very serious, and if it gets too bad, it can cause a thyroid storm, coma; even death. So if you have it, take care of it.
