7.Heart Failure
If your heart can’t pump blood and oxygen to the rest of your body like it should, your digestive system may not get enough blood to do its job well. This can make you feel full even when you haven’t eaten and may make you sick to your stomach. Eventually, your body might not be able to get rid of fluid like it should, and it can build up in your intestines and keep you from taking in nutrients. Your doctor may recommend that you cut down on salt and give you medicines called diuretics that help you clear out the fluid.
8.Dementia
This weakens your ability to think along with your basic memory and social skills. In later stages, you may lose a lot of weight because you forget to eat or find it harder to chew or swallow. Chronic infections, special diets, and drugs used to treat dementia can make it worse.
