A female child, growing up eating normal foods and drinks in mediocre quantities, will attain puberty at the ‘right’ age of about 12. From then on, she would have uncomplicated menstrual discharges regularly at monthly intervals.
The above situation changes if the girl happens to habitually under- or over-urinate.
Under-urinations lead to the accumulation of calcium in various parts of the body, and adversely influences the attainment of her puberty and also the subsequent monthly discharges. The former gets delayed, and the latter becomes erratic.
Consumption of excessive water (about 3 L), and over-urination lead to the depletion of most of the wanted nutrients from the body. This prompts the body to attain an early maturity, and subsequent menstruations become erratic, with severe pain – the Pre-menstrual Tension (PMT).
Strenuous exercises that induce the secretion of the Thyroid Stimulating Hormone (TSH) and influence the production of the female hormone oestrogen, the intake of synthetic drugs in the names of vitamins, minerals and food supplements, etc. would also disorganise the menstrual pattern in a female.
