The problem of overweight is real and significant, and this is particularly true in the United States. According to the numbers, in the US over sixty-five percent of people are overweight. Perhaps a more dramatic way of presenting this information is that only thirty-five percent of people in the US are not overweight. Naturally, these percentages translate into millions and millions of people. One could reasonably argue that this represents a massive potential health crisis, and so the availability of information about overweight health risks is not only understandable but perhaps even necessary.

The majority of Americans realize that there is a correlation between overweight and health difficulties. Some of the health problems linked to overweight include increased risk of heart attack, stroke, diabetes, and even certain kinds of cancer. There is an additional problem linked to overweight that typically doesn't get much consideration however: the link between women being overweight and a difficulty with getting pregnant.

Having trouble getting pregnant may not seem as significant as having a heart attack or stroke, but it is a real consideration for some people. Though the data is not necessarily clear-cut, there seem to be a number of reasons why overweight women can have difficulty conceiving. One reason may have to do with a particular hormonal imbalance. Leptin is a hormone that's typically deficient in people who are overweight. Leptin is thought to play a role in appetite regulation and energy levels. Leptin may also be linked to fertility levels in women: the lower the levels of Leptin in a woman's body, the more difficult it may be for a woman to conceive.

The ovulation cycle involves a second connection between overweight and infertility. Women who are overweight and obese can have ovulation cycles that are abnormal and even non-existent. The problem here of course is that ovulation is when a woman's fertility capacity is replenished and renewed. Without the capacity for fertility to begin with, pregnancy is not just difficult but impossible. Lastly it's possible that women who are significantly overweight may not have the overall good health needed to conceive a child. Despite what some people may believe, conception isn't guaranteed: among women, those who are younger and in good health are more likely to become pregnant.

It's important to bear in mind that weight gain during a pregnancy is an absolutely normal and appropriate process. What may be problematic is excess body weight before pregnancy takes place. Not only may a normal body weight increase the odds of conception occurring, it will also almost certainly improve the likelihood for a healthy and normal pregnancy term.
