These are symptoms of a pituitary adenoma. A tumour in the pituitary gland can compress the optic chiasm, causing blindness in the peripheries of both eyes (bitemporal hemianopia). If the pituitary adenoma produces excess prolactin, known as a prolactinoma, it can also cause erectile dysfunction and gynaecomastia (discharge from the nipple in men).

These are symptoms that are characteristic of hypothyroidism - a decrease in thyroxine levels in the body.

Thyroxine is responsible for regulating the body's metabolism, and a decrease in thyroxine slows metabolism down, explaining why a person may always feel cold (cold-intolerance), be low in mood and feel tired.

Cushing's syndrome is caused by an excess production of the hormone cortisol. Cortisol is produced in the early mornings to wake us up. It is also produced in times when we are stressed, to increase the levels of glucose in the bloodstream available for cells to use.

An excess of cortisol will produce the symptoms listed above, and therefore these are the symptoms you would expect to find in Cushing's syndrome.
