If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.
Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.
Conditions that may lead to anemia include
- Heavy periods
- Colon polyps or colon cancer
- Inherited disorders
- A diet that does not have enough iron, folic acid or vitamin B12
- Blood disorders such as sickle cell anemia and thalassemia, or cancer
- Aplastic anemia, a condition that can be inherited or acquired
- G6PD deficiency, a metabolic disorder
Anemia can make you feel tired, cold, dizzy, and irritable. You may be short of breath or have a headache.
Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have.

Iron is a mineral that our bodies need for many functions. For example, iron is part of hemoglobin, a protein which carries oxygen from our lungs throughout our bodies. It helps our muscles store and use oxygen. Iron is also part of many other proteins and enzymes.
Your body needs the right amount of iron. If you have too little iron, you may develop iron deficiency anemia. Causes of low iron levels include blood loss, poor diet, or an inability to absorb enough iron from foods. People at higher risk of having too little iron are young children and women who are pregnant or have periods.
Too much iron can damage your body. Taking too many iron supplements can cause iron poisoning. Some people have an inherited disease called hemochromatosis. It causes too much iron to build up in the body.

If you have a swallowing disorder, you may have difficulty or pain when swallowing. Some people cannot swallow at all. Others may have trouble swallowing liquids, foods, or saliva. This makes it hard to eat. Often, it can be difficult to take in enough calories and fluids to nourish your body.
Anyone can have a swallowing disorder, but it is more common in older adults. It often happens because of other conditions, including
- Nervous system disorders, such as Parkinson's disease and cerebral palsy
- Problems with your esophagus, including GERD (gastroesophageal reflux disease)
- Head or spinal cord injury
- Cancer of the head, neck, or esophagus
Medicines can help some people, while others may need surgery. Swallowing treatment with a speech-language pathologist can help. You may find it helpful to change your diet or hold your head or neck in a certain way when you eat. In very serious cases, people may need feeding tubes.
