When an infant is choking and becomes unresponsive, the five-and-five approach is recommended as a first aid treatment to dislodge the material blocking the airway.

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- <u>anterior pituitary gland and posterior pituitary gland</u>. 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 <em>TSH, Prolactin, Luitenizing Hormone, Cortisol, Testosterone</em>, etc.
Cortisol is produced by the <u>adrenal gland</u> under the command of <em>pituitary gland</em>. Cortisol helps in <em>regulating blood sugar, blood pressure</em> 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.
