What’s causing my loss of appetite and nausea?
The first thing to understand is that there are many reasons why one may lose their appetite or experience symptoms like vomiting, diarrhea, cramps, etc. These symptoms are not necessarily due to some disease or illness. They could just be part of normal aging.
It is very common for people over age 50 to experience these types of symptoms, but they do not always mean that something is wrong with your body. Some people simply develop them later in life because of certain medical conditions such as diabetes mellitus (type 2), cancer, heart problems, stroke, etc.
However, if you are experiencing any of these symptoms, it is best to see a doctor immediately. Your doctor will be able to determine what is going on and possibly treat the underlying cause.
There are several things that can cause sudden loss of appetite or other symptoms:
1) A physical condition that affects your digestive system.
For example, if you have Crohn’s disease or ulcerative colitis then you might experience severe abdominal pain and bloating. Additionally, you might experience symptoms like nausea, vomiting, and diarrhea.
2) Thyroid problems such as hyperthyroidism or hypothyroidism can also cause changes in your appetite (such as loss of appetite).
In addition to change in your appetite, you might also experience other symptoms such as weight loss, fever, rapid heartbeat, fatigue, etc.
3) Some forms of cancer can also affect your appetite.
