Answer:

Weight gain and depression are symptoms caused by imbalance of pituitary and adrenal glands and the cortisol hormone.

Explanation:

The pituitary gland is responsible for the overall functioning of the body since it produces a variety of hormones. It is very small in size and is also known as the 'master gland'. It is made of two parts- anterior pituitary gland and posterior pituitary gland. The pituitary gland and its functions are controlled by the hypothalamus.

The anterior pituitary secretes hormones which act on adrenal glands, thyroid, testes and ovaries. The hormones produced are TSH, Prolactin, Luitenizing Hormone, Cortisol, Testosterone, etc.

Cortisol is produced by the adrenal gland under the command of pituitary gland. Cortisol helps in regulating blood sugar, blood pressure and helps in reducing inflammation. Any imbalance of adrenal gland will cause an increase or decrease in the production of cortisol. The symptoms produced on the imbalance are:

Obesity in upper body
High blood pressure
Mood swings, depression and irritability
Acne and other skin problems.
