There are several possibilities for your weight gain, and this amount of weight gain really does require you to talk with your doctor
to make sure there is no underlying medical condition causing the weight gain. To begin, it would be helpful to think back to your food and exercise regimen over the last several months. You may even want to keep a diary of what you are eating and what exercise you do. This information will be helpful to you and your doctor as you try to figure out whether most of the weight gain is due to lifestyle or to other medical factors. Abdominal cramps with weight gain are suggestive of a few things. Perhaps the most common would be constipation, which can produce abdominal cramps, and is associated with hypothyroidism, one of the most common causes of weight gain. Other symptoms of a hormonal, thyroid or otherwise, cause of weight gain would include changes in your body hair patterns, changes in the color and texture of your skin, and stretch marks or fat in unusual places such as between your shoulder blades. Another possibility would be an abdominal mass, such as an ovarian tumor, especially if you have abdominal bloating or distention. Regardless, the first step is to set up a visit with your internist
as soon as possible!
