A Lump in the Throat
When food cannot glide down the gullet as usual, it is important to have it checked. This is particularly important when the symptom becomes more serious over time. Sometimes, you can find it even more difficult to swallow water. A lump or pain in the throat could indicate the presence of a severe GI issue. A GI doctor can check to know whether your swallowing problems are accompanied by hiccupping, hoarseness, coughing, or fullness after several bites. In some cases, esophageal cancer might be the main cause. [3]
Reduced Iron Levels
Iron plays a key role in helping red blood cells transport oxygen to other parts of the body. When iron levels are lows, you can feel extremely tired. Other symptoms include overall weakness, hair loss, brittle nails, yellowish skin, and headaches. In these cases, you might need to visit a GI doctor. He or she can check for signs of iron deficiency anemia, which can be caused by a loss of blood in the GI tract. Possible causes include ulcers, stomach cancer, angiodysplasia, inflammatory bowel disease, as well as colon cancer. [4]
