what effects does rice have on mensturation?

Hi,
Welcome to ehealthforum,
Changes in diet, lifestyle, exercise pattern, stress levels can affect hormonal pattern causing changes in your period pattern. If you are not pregnant, and if you are having irregular periods or missed periods, the causes could include obesity, increased body fat percentage, brain or pituitary tumors, PCOS, premature ovarian failure, thyroid dysfunction, use of certain medications, hormonal imbalances, etc. You should consider visiting your doctor/gynecologist for further evaluation and assistance. Treatment as appropriate (based on examination findings and investigations results) would be started to help you get your periods and regulate them. You can also consider getting semen analysis done for your partner to look at the quality and quantity of sperms produced. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
