Coffee, tea and some cola drinks contain caffeine.
This is a stimulant and is responsible for the lift most people experience after drinking these beverages, but too many cups may make you tense and irritable and keep you awake if you drink them late at night.
Caffeine tends to constrict the blood vessels and, when the effect wears off, a rebound dilation of the scalp arteries may cause a throbbing headache. Many of the combination analgesic tablets and powders also contain caffeine and can relieve the headache by causing further arterial constriction.
But, when this wears off, headaches may recur.
Analgesic abuse is often related to the regular taking of analgesic tablets and powders for the “lift” experienced, then a rebound headache provides the justification for taking more analgesics.

The middle-aged spread is common and its cause is debated. It may be due to hormonal factors but is more commonly due to over-eating and less exercise.
Even if the cause is hormonal, it can still be corrected by proper dietary advice.
Once the periods have stopped and the woman has become post-menopausal, late changes may arise from the lack of oestrogen. The bones may lose their protein matrix and, with it, some of their calcium. This is called osteoporosis and the bone is thinner and weaker.
Lack of oestrogen may cause changes in the vaginal walls. The skin lining may become thickened and less moist. This may lead to irritation, infection, a discharge or an intolerable itch. Intercourse becomes difficult.
Similar changes may involve the urethra, the tube which carries the urine from the bladder to the outside. These changes may lead to frequency and pain on passing urine. This is commonly called cystitis but is due to irritation.
