Hormones- All hormones must be in a balanced state so that they do not cause bad effects on the body’s systems or make them unfit for use.

As reported by Ehow, NLM, MedicineNet, and netdoctor, of the hundreds of hormones available, here are the 10 most important hormones in the human body, namely:


This hormone is produced in the pineal gland and functions as an antioxidant and controls sleep. A deficiency or a lack of this hormone can cause insomnia, difficulty sleeping or insomnia, mood swings, and other physical and psychological problems.


Serotonin hormone is produced in the digestive tract. Therefore, this hormone functions to control mood or mood, appetite, and sleep.

Excess serotonin can cause anxiety, confusion, increased heart rate, dilated pupils, loss of muscle coordination, sweating, diarrhea, vomiting, seizures, high fever, irregular heartbeat, uncontrollable movements, and loss of consciousness, according to the National Institute of Mental Health (NIH).

Serotonin deficiency can cause anxiety, depression, phobias, pessimism, restlessness, insecurity, irritability, sleep disturbances, PMS, headaches, and backaches.


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

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

Some can even cause depression and other mental disorders, according to the National Institutes of Health (NIH).


Adrenaline is produced in the adrenal medulla. Therefore, this hormone functions to increase the supply of oxygen and glucose to the brain and muscles (by increasing heart rate), increase the catalysis of glycogen in the liver, break down lipids in fat cells, and suppress the immune system.

So, a Lack of adrenaline can cause dizziness, dizziness, fatigue, and weight loss. Some experience intestinal disturbances, increased skin pigmentation, depression, muscle aches, and acute back pain.


Production of this hormone in the kidneys and hypothalamus. So, Excess dopamine can cause nausea, vomiting, headache, irregular heartbeat, chest pain, difficulty breathing, changes in the amount of urine, and changes in skin color. Lack of dopamine can lead to depression, low motivation, difficulty paying attention and concentrating, slow thinking, low libido, and impotence.


Production of this hormone in the duodenum (12-finger intestine), which functions for the secretion of gastric acid by parietal cells. So, Excess gastrin can cause gastrinoma, which is a benign tumor.

Growth hormone (HGH)

Excess growth hormone can cause a tumor that is benign and grows slowly. It can also cause headaches, pressure on the optic nerve, excess jawbone, fingers and toes, muscle weakness, and insulin resistance. In adults, growth hormone deficiency is rare but can lead to obesity, decreased muscle mass, and reduced energy.


Production of this hormone in the pancreas and functions for glucose uptake, glycogenesis, and glycolysis in the liver and muscles from the blood.

Excess insulin can cause very low blood sugar levels, irregular heartbeat, sweating, tremors, nausea, severe hunger, and anxiety. Sometimes it also causes hypoglycemia (low blood sugar).

Lack of insulin can cause hyperglycemia (increased blood sugar levels) which can lead to diabetes mellitus.


Production of this hormone in the testes and functions as a male sex hormone. This hormone stimulates the maturation of the male sex organs, the scrotum, the growth of the beard, the growth of muscle mass and strength, and an increase in bone density.

Excess to this hormone can cause excessive libido increase and irritability. Testosterone deficiency can cause disease or damage to the hypothalamus (pituitary gland) or testes that inhibits hormone secretion and testosterone production (hypogonadism).

Lack of testosterone can also make wrinkles on the face, loss of body muscle, waist fat, chronic fatigue, decreased libido, erectile dysfunction and difficulty achieving orgasm can occur in both men and women.


Production of this hormone in the ovaries, adrenal glands, and placenta (during pregnancy).

The hormone progesterone increases epidermal growth factor, increases core temperature during ovulation, reduces spasms and relaxes smooth muscles (expands the respiratory tract and regulates mucus), is anti-inflammatory, and reduces gallbladder activity. Progesterone also helps thyroid function and bone growth with osteoblast resilience in bones, teeth, gums, joints, tendons, ligaments, and skin.

Progesterone deficiency can cause anxiety, insomnia, difficulty resting, panic, restlessness, lack of fluids, and swollen breasts.
