It’s important to note that there are several medical conditions that make it hard or even impossible to lose weight. Though these conditions are rare, they can seriously impact your quality of life until they are diagnosed and treated.
Some of the most common medical reasons for weight gain (or slow weight loss) include Cushing’s disease; hypothyroidism; insulin resistance (or pre-diabetes); and, for women, polycystic ovary syndrome.
Fortunately, all of these conditions can be diagnosed with simple blood tests. Once you have a diagnosis, you and your health care provider can decide on a good course of treatment. As the condition improves, your weight loss will progress more normally.
Sometimes medical treatments are the culprits behind weight gain. If you take oral steroids, you might find it very difficult to lose weight or even avoid gaining weight. Some birth control methods, such as depo-provera injections, are also linked to weight gain.
Speak with your doctor about treatment alternatives. Medical research has given us plenty of new drugs to choose from, so chances are good that you can use one which will not stall your weight loss.
