Anemia is defined as a low number of red blood cells. In a routine blood test, anemia is reported as a low hemoglobin or hematocrit. Hemoglobin is the main protein in your red blood cells. It carries oxygen, and delivers it throughout your body. If you have anemia, your hemoglobin level will be low too. If it is low enough, your tissues or organs may not get enough oxygen. 

Anemia affects more than two billion people globally, which is more than 30% of the total population. It is especially common in countries with few resources, but it also affects many people in the industrialized world. Within the U.S., anemia is the most common blood condition. An estimated three million Americans have the disorder.

Anemia can have other affects on your body in addition to feeling tired or cold. Other signs that you might be lacking in iron include having brittle or spoon-shaped nails and possible hair loss. You might find that your sense of taste has changed, or you might experience ringing in your ears.

Different types of anemia may lead to other serious problems. People with sickle cell anemia often have heart and lung complications.

Bloating is a condition where your belly feels full and tight, often due to gas. When you are bloated, you feel as if you’ve eaten a big meal and there is no room in your stomach. Your stomach feels full and tight. It can be uncomfortable or painful. Your stomach may actually look bigger. It can make your clothes fit tighter.

Bloating happens when the GI tract becomes filled with air or gas. This can be caused by something as simple as the food you eat. Some foods produce more gas than others. It can also be caused by lactose intolerance (problems with dairy). 

Your doctor can generally diagnose the cause of your bloating through a physical exam in the office. He or she will ask you questions about your symptoms. They will want to know if your bloating is occasional or if it occurs all the time.

Temporary bloating is usually not serious. If it happens all the time, your doctor may order other tests. These could include an imaging test to look inside your abdomen. This could be an X-ray or CT scan.

The stomach flu (gastroenteritis) is a nonspecific term for various inflammatory problems in the gastrointestinal (GI) tract.

Food allergies may produce eosinophilic gastroenteritis, a sign of which is increased eosinophils (a type of white blood cell) seen in the blood. Children with the stomach flu or gastroenteritis have similar symptoms to adults, but also may have symptoms such as refusing to drink or being very thirsty.

The main way contagious causes of the stomach flu are spread is person to person via the fecal-oral route. Individuals at most risk of catching the stomach flu are those in close association with an infant, child, or an adult that has a viral or bacterial cause of stomach flu .

Stomach flu is diagnosed in most cases without specific tests, however, tests can help define the underlying cause. Home remedies may reduce symptoms of stomach flu, including diet changes. Most people with viral or mild bacterial gastroenteritis require no treatment. Some individuals may require symptom reduction with medications but more serious bacterial infections may require antibiotic therapy.
