10 Important Hormones for the Human Body


Health TipsThe human body consists of various hormones which have their respective functions. All portions of the hormone must be balanced so as not to cause adverse effects to the body.

As quoted from eHow, NLM, medicinenet, and netdoctor, Monday (19/4/2010), from hundreds of hormones, there are 10 most important hormones in the human body, namely:

1. Melatonin
This hormone is produced in the pineal gland and functions as an antioxidant and sleep control. Although this hormone is produced naturally by the body, but excess or lack of these hormones can be bad for the body.

Excess of melatonin hormone can cause sluggish, liver disorders, eye disorders, fatigue, disorientation, psychotic thoughts and behavior, confusion, drowsiness, impaired speaking, shaking, headache and dizziness.

While the melatonin hormone deficiency will cause difficulty in sleeping or insomnia, prostate enlargement, depression, fatigue, irregular menstrual cycles, anxiety, premenstruasi syndrome (PMS), cataracts, high cholesterol, high blood pressure, arrhythmia.

2. Serotonin
The serotonin hormone is produced in the digestive tract. This hormone serves to control mood, appetite and sleep.

Excessive serotonin hormone can cause anxiety, confusion, increase heart rate, widened pupils, loss of muscle coordination, sweating, diarrhea, headache, chills, nausea, vomiting, convulsions, high fever, irregular heartbeat, uncontrolled movements and loss of consciousness.

Deficiency of serotonin hormone can cause anxiety, depression, phobias, pessimistic, insecure, lack confidence, irritability, sleep disturbances, PMS, headache and backache.

3. Thyroid
Thyroid hormones are produced in the thyroid gland. This hormone functions to increase the basal metabolic rate and affect protein synthesis.

Excessive thyroid hormone can cause diarrhea, irregular heartbeat, headache, chills, nervousness, stomach cramps, fever, chest pain, or difficulty sleeping.

While deficiency of thyroid hormone can cause fatigue, weakness, constipation, sore joints and muscles, ramput or thin, brittle nails, lack of sex drive, high blood pressure, high cholesterol, slow heartbeat, impaired concentration and memory. Even a few can cause depression and other mental disorders.

4. Adrenalin
Adrenal hormones are produced in the adrenal medulla. This hormone functions to increase the supply of oxygen and glucose to the brain and muscles (by increasing heart rate), increasing catalysis of glycogen in the liver, damage to lipids in fat cells, and suppresses the immune system.

Lack of adrenal hormones may cause dizziness, headache, fatigue, weight loss. Some experience intestinal disturbances, increased pigmentation of the skin, depression, muscle pain and acute back pain.

5. Dopamine
This hormone is produced in the kidney and hypothalamus. This hormone functions to raise your heart rate and blood pressure, inhibiting the release of prolactin and TRH from anterior pituitary.

Excess of dopamine may cause nausea, vomiting, headache, irregular heartbeat, chest pain, difficulty breathing, changes in the amount of urine, skin discoloration, pain in legs and arms.

Hormone dopamine deficiency can cause depression, low motivation, difficulty paying attention and concentrating, slow thinking, low libido and impotence, tiredness, rapid weight increase, and sleep disturbance.

6. Gastrin
This hormone is produced in the duodenum (intestine 12 fingers), which functions for gastric acid secretion by parietal cells.
Excess of gastrin can cause gastrinoma disease.

7. Growth hormone (HGH)
This hormone is produced in the anterior pituitary, and serves to stimulate the growth and reproduction of cells, release of insulin-like growth factor 1 from liver.

Excessive growth hormone can cause pituitary tumors which are benign and grow slowly. Also can cause headaches, visual disturbances, optic nerve pressure, excess jaw, fingers and toes, muscle weakness, insulin resistance. It could even lead to diabetes type 2 and decreased sexual function.

deficiency of this hormone in children can cause growth failure and short body and delayed sexual maturity. Whereas in adult growth hormone deficiency is rare, but in some cases can lead to obesity, decreased muscle mass and energy reduction and quality of life.

8. Insulin
This hormone is produced in the pancreas and functions to capture glucose, glikogenesis and glycolysis in liver and muscle from the blood.

Excessive insulin can cause low blood sugar levels, irregular heartbeat, sweating, tremor, nausea, severe hunger and anxiety. Sometimes also cause hypoglycemia (low blood sugar).

Insulin deficiency can cause hyperglycemia (elevated blood sugar levels) that leads to diabetes mellitus.

9. Testosterone
This hormone is produced in the testes and serves as the male sex hormone. This hormone stimulates the maturation of male sex organs, scrotum, beard growth, the growth of muscle mass and strength, and increase bone density.

Excess of this hormone can cause increased libido, and excessive irritability. Lack of testosterone can cause disease or damage to the hypothalamus (pituitary) or testicles that inhibits hormone secretion and production of testosterone (hypogonadism).

Testoreton deficiency can also create wrinkles in the face, loss of muscle tone, large waist, chronic fatigue, decreased libido, erectile dysfunction and difficulty reaching orgasm can occur in men as women.

10. Progesterone
This hormone is produced in the ovary, adrenal gland and placenta (when pregnant). Progesterone serves to increase epidermal growth factor, increases core temperature during ovulation, reduces spasms and to relax smooth muscle (widen bronchi and regulate mucus), anti-inflammatory, reduces gallbladder activity, normalization of clotting blood and blood vessels.

Progesterone hormone also helps thyroid function and bone growth by osteoblasts Relsilience in bone, teeth, gums, joints, tendons, ligaments and skin. Healing by regulating collagen nerve function and healing by regulating myelin, and to prevent endometrial cancer by regulating effects of estrogen.

Lack of progesterone can create anxiety, insomnia, difficulty resting, panic, anxiety, lack of fluids and breast swelling.
