Hello,
Weight gain after a cancer diagnosis is more common than most people realize. Many people believe that all cancer patients will struggle to eat enough and are likely to lose weight during and after treatment. This may have been true in the past, but it is not the case anymore.
Certainly, some people being treated for cancer will struggle to eat well and do need assistance to make sure they get good nutrition during and after treatment. In these cases, it is vitally important to see a qualified nutrition professional such as a registered dietitian for assistance. But for many in cancer care, this is not the case.
There are many excellent medications available to manage the side effects of cancer treatment such as nausea, vomiting, and lack of appetite, which in the past, may have lead to weight loss. When these symptoms are under control, many people can eat their normal diet and aren't likely to lose weight.
A surprising effect of this ability to eat normally is that some people actually gain weight. Adding to this problem is the fact that some medications may even increase appetite making it harder to manage weight during cancer care. Weight gain tends to be most common in people with early stage cancers of the breast and prostate, although anyone can gain weight during treatment.
If you have gained just a few pounds, for example 3 or fewer pounds, I would not be overly concerned. A small amount of weight gain is not likely to significantly affect your long term health, so long as you don't keep on gaining. However, if you are not underweight and you have gained more than 3 to 5 pounds, you should make an effort to address this issue before you gain so much weight that it negatively affects your health.
More and more, health experts are finding that gaining weight during and after cancer treatment can significantly worsen health. Carrying excess weight puts additional stress on the body. Studies tell us that this extra stress makes it harder for your body to fight the cancer, heal, recover, and remain healthy for the long-term. People who gain weight during and after cancer treatment may be more susceptible to cancer recurrence or another cancer diagnosis, and they are more likely to suffer from other chronic health conditions such as heart disease, high blood pressure, diabetes, and stroke.
For all of these reasons, maintaining a healthy body weight should be a high priority for all cancer survivors. In reality, this should be a high priority for ALL people, regardless of whether or not they have had cancer.
For cancer patients, as with all people, there are two things that affect body weight: 1) How much you eat and 2) How much physical activity (exercise) you get.
One thing that is important to know is that early research tells us it is the lack of activity during cancer treatment that may contribute the most to uncontrolled weight gain. This isn't surprising given how common fatigue is for those in cancer care. Being fatigued makes it harder to move your body. Being fatigued makes it harder to make the effort to get out and take a walk or do other things you normally do.
The good news is that getting some physical activity will help both problems. Those who are most active during treatment have the least fatigue. As well, getting physical activity will help you avoid unhealthy weight gain.
First, be sure to get the OK from your doctor or nurse that it is safe for you to exercise. Second, remember that you do not need to go out and run a marathon to get the benefits of physical activity. Simply walking is one of the best ways to keep your body healthy. In addition to walking, you may want to ask your doctor if it is ok to do some resistance or strength training.
Most people think of strength training as "lifting weights", but you don't need to lift weights if that is not convenient for you. You can use resistance exercise bands (stretchy tubes of rubber) or the weight of your own body while doing walking lunges, pushups, or squats. If you are uncertain how to begin, ask your doctor for a referral to a physical therapist or exercise physiologist. It likely will take only 1 to 3 sessions to get a program that you can do yourself at home.
In fact, one research study conducted at Duke University has found that a home exercise program can help cancer patients maintain strength and avoid weight gain during cancer care.
In addition to moderate physical activity, you should eat a healthy, balanced diet. The more vegetables, fruit, whole grains, and legumes (beans) you can eat, the better. These foods are healthy and filling, so they keep you from eating more calories than you need.
