Are You Too Thin to Conceive?

woman thinking

While the association between infertility and being significantly overweight is pretty clear, the relationship between being underweight and having trouble getting pregnant is not as clear. There are certain situations in which very thin women do have trouble conceiving, usually because they do not ovulate. Athletes who are training heavily may not ovulate. If they do not ovulate, they cannot get pregnant. Women with anorexia nervosa also do not ovulate normally. However, the answer to the question of whether or not you are too thin to conceive is probably no, as long as you are otherwise healthy, eating a nutritious diet, and exercising moderately.

There is a complex relationship between female hormones and hormones from the pituitary and other parts of the brain. It is relatively easy to disrupt the normal cycle of hormone release. With intense exercise, there is a disturbance in the way the brain releases hormones which can interfere with ovulation and menstruation.

    My sister is anorexic and bulimic she is 5’6nand was 85lbs when she checkout of hospital without doctors approval. Two months later she had put on a few pounds maybe weighed 90lbs her doctor told her she couldn’t get pregnant. She was 22 at the time and it wasn’t planned but she was pregnant. The pregnancy saved her life because she ate a bit better for 9 moths anyway. Day after having her daughter it looked like she was never pregnant. But she has a beautiful daughter now. She still struggles from week to week I don’t think the disease will ever really leave her but I don’t think it will take her over again either, I hope.

    This was very informative. I knew overweight women could have problems conceiving, but I didn’t know that thin women could as well.

  3. My sister deals with this. She is thin, but not extremely thin. My family is very tall and have fast metabolisms. She eats normally, some say she eats a lot. But her periods are irregular because she is “too thin” to produce fat around her ovaries.
