Common symptoms of digestive disorders in adults and children are bowel disorders, abdominal pain, indigestion, due to an imbalance of intestinal bacteria, leading to intestinal dysbiosis.

I am male, 20 years old this year. These days, I have symptoms of eating quickly, I feel full, after eating, I feel no digestion, and my stomach is full. Walking is still normal. After eating, the stomach is tight and slightly throbbing in the upper abdomen. So the doctor asked me, if I eat quickly, I can't digest it, is it a digestive disorder? Looking forward to the doctor's advice, thank you!

Anemia is a condition in which the body does not have enough healthy red blood cells to supply oxygen to the body's tissues. There are different types of anemia with different causes and pathogenesis. Biermer's pernicious anemia is a form of macrocytic anemia, which occurs when the number of red blood cells is reduced and abnormal in size as a result of the intestinal mucosa not being able to properly absorb vitamin B12.
