Is is possible to lose your period permanently? (I am 17, have had no periods for 1.5yrs - my periods started at 10 - I am also at a healthy BMI).

Yes, possible: Most likely you have stopped ovulating and this is the reason your periods have stopped. There are plenty of women with PCOS (polycystic ovarian syndrome) who have a normal BMI. There are also other endocrine reasons for anovulation (i.e. thyroid disease). Very rarely, some women have early ovarian failure. You should see your physician because it needs to be regulated (like with BCPs). ...Read more

My weight is 66kg now. I want to reduce it to 60 kgs over a period of one year from now. Can I do that even my BMI is average? What is the best method

My weight is 66kg now. I want to reduce it to 60 kgs over a period of one year from now. Can I do that even my BMI is average? What is the best method

Slow and consistent: Losing 6 kg (~13 lb) over a one year period of time is reasonable. That is only a decrease of about 3500 calories a month or a little over a 100 calories a day. Start by reducing or eliminating any high calorie drinks such as soda, juice or alcohol. Start a consistent walking program, minimize fast food, concentrate on whole foods: lean meat, veggies and fruit. Have a cheat meal every now and then. ...Read more

At what point in time would an anorexic regain her period? BMI at 18.2. Originally weight at 18.7. Is low carb, high fat and protein diet beneficial?

At what point in time would an anorexic regain her period? BMI at 18.2. Originally weight at 18.7. Is low carb, high fat and protein diet beneficial?

BMI 18: I can't answer your question about periods, but a BMI of 18 is normal (18-25) and a low carb, high fat, protein diet perfectly okay. You should be trying to match your caloric need to your calories consumed. For example, if you're 5 feet, 5 inches (165 cm), at 18, your estimated caloric need is roughly 1600 to 1800 calories a day. Aim for that. ...Read more

If I only have a BMI of 17.5 from eating unhealthy will be on my period harm me. I'm scared I will faint or die because I always have heavy bleeding.

If I only have a BMI of 17.5 from eating unhealthy will be on my period harm me. I'm scared I will faint or die because I always have heavy bleeding.

Harm: A low bmi can mean that you don't have a lot of estrogen. It sounds like you have heavy bleeding, so you may be Progesterone dominant and not enough estrogen to stabilize lining of uterus to have normal cycle. Low bmi also put you at increased risk bone loss. Why not eat healthy? Do you have an eating disorder? There are great therapists if that is the case, see one, get some help. ...Read more

I had unprotected sex on friday and got my period on sunday is it spotting could I be pregnant I have irregular periods and my BMI is 16 97?

Too early: Since you had sex 3 days ago it is way to soon to know if you are pregnant. You should check a pregnancy test in 7-10 days to know. We usually suspect pregnancy when you miss your period not when you have one. Plan b is helpful to prevent if you are within 72 hrs of sex. Start birth control to prevent scares. ...Read more
