Thyroid Problems & Disease
Are you suffering from thyroid problems
Functions of Thyroid
The thyroid is a butterfly-shaped gland in your neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid hormones control the rate of many activities in your body. These include how fast you burn calories and how fast your heartbeats. All of these activities are your body’s metabolism. The basal metabolic rate (BMR) is defined as the amount of heat produced in the body in a given time, incomplete state of physical and mental rest at 20°c room temperature.
Actions Of Thyroxine
• This hormone is very essential for the development of the nervous system particularly at the time of birth and during the first year
• This hormone increases the metabolism of all tissues except the brain, gonads, and accessory sex organ, lymph nodes, spleen, and lungs
• The most important function is to increase the absorption of glucose from the small intestine
• This hormone reduces serum cholesterol level
• It promotes protein anabolism, and help in growth
• It increases the heartbeat rate, the force of contraction, and pulse pressure,
• Presence of optimum level of thyroxine in the blood maintains efficient muscle functions and,
• The optimum level of thyroxine in the blood is also necessary for normal gonadal function.
Thyroid Problems Include
Diseases of the thyroid cause it to make either too much or too little of the hormone. Depending on how much or how little hormone your thyroid makes, Women are more likely than men to have thyroid diseases. It makes your periods very light, heavy, or irregular. a person may often feel restless or tired, or you may lose or gain weight.
Hypothyroidism or under-active thyroid or non-functioning thyroid gland
The physiological effect due to deficiency of thyroid hormone is referred to as hypothyroidism.
It is manifested by iodine deficiency and simple goiter, Cretinism and Myxedema.
If the dietary intake of iodine becomes inadequate (below 10 micrograms per day) the synthesis of thyroxine is impaired. As a result, the thyroxine level falls in circulation and secretion of THS increases, causing the hypertrophy of the thyroid gland as a consequence.
The thyroid enlarges to enormous proportions. This is called a simple goiter. This condition is also called endemic goiter. It is caused due to lack of iodine in the soils of a different region of the world.

- trouble sleeping

- protrusion of eye balls from the sockets (exophthalmas) redness, or irritation
- increased heart beat rate
- eating more than usual
- lighter menstrual periods than normal
- emotional instability
- weight loss
- increase blood glucose and decreased serum cholesterol
- risk for osteoporosis
- derangement of sexual function etc
