Another request by a regular Fat Creep reader; please keep your queries coming guys, I've been responding to requests for the last month straight and I love that.
The simple answer is yes BUT if your periods have stopped, it's very unlikely that the cause is too much exercise. It is very difficult to exercise 'too much' especially if you have a desk job. However, a highly restricted diet is much more likely to stop your periods.
Amenorrhea is the term given to a cessation of periods. It is common in people suffering from anorexia, models who aren't eating enough and athletes who aren't replenishing their bodies adequately.
Why exactly do periods stop if you're not eating enough?
Your body goes into starvation mode.
This means it shuts down the activity of all unnecessary bodily functions and organs. This includes the reproductive system as well as nutrition to hair and nails. To stop your periods from occurring the hypothalamus stops releasing the hormones involved in the regulation of periods. This then causes a reduction in oestrogen and progesterone, the main female sex hormones.
What are the consequences of your periods stopping due to a poor diet?
In the long-run a lack of oestrogen and progesterone could result in:
What should you do if your periods have stopped?
What should you be eating?
In summary, if your periods have stopped it's likely due to a poor diet and/or an underlying medical problem e.g. Polycystic Ovarian Syndrome, PCOS.
