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 overweight women and an inability to conceive children.

Though the idea of bearing children may not seem as dire as having a stroke or a heart attack, pregnancy is an important goal for many 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.

A second link between overweight and a difficulty getting pregnant is thought to be the ovulation cycle. 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. If infertility is not a viable option to begin with, pregnancy is certain to never occur. A final possibility is that a woman who's considerably overweight simply may not possess the good health needed for the conception process to take place. 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. In addition to making pregnancy more likely, a normal body weight will also positively affect the outlook for a healthy pregnancy overall.
