The connection between low iron, body weight, and hemoglobin is apparent when low energy makes exercising and burning calories difficult, causing weight gain. Conversely, iron deficiency anemia may contribute to decreased appetite, resulting in weight loss.
Iron deficiency anemia (IDA) is associated with decreased appetite. The ghrelin hormone is one of the major regulators of appetite.
The thyroid produces certain hormones that regulate the body's metabolism, so an excess of these hormones often causes the body to burn more energy than usual. Burning more energy and calories can lead to unintentional or unexplained weight loss. Other symptoms of hyperthyroidism include: fatigue.

If you suspect you might have an anemic disorder, check yourself for the following symptoms and call your doctor for further advice. A sudden lack of energy and chronic fatigue are warning signs that you might be lacking enough iron.
If you have anemia, your body does not get enough oxygen-rich blood. The lack of oxygen can make you feel tired or weak. You may also have shortness of breath, dizziness, headaches, or an irregular heartbeat.
Cancers Linked to Anemia
Leukemia and lymphoma are cancers that affect your bone marrow. That's where all your blood cells come from. These conditions disrupt your body's process for making red blood cells. So there's not enough of them to carry oxygen to other parts of your body.
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.
Abstract. Iron deficiency impairs skeletal muscle metabolism. The underlying mechanisms are incompletely characterised, but animal and human experiments suggest the involvement of signalling pathways co-dependent upon oxygen and iron availability, including the pathway associated with hypoxia-inducible factor (HIF).
Key points about vitamin B12 deficiency anemia
Without enough oxygen, your body can't work as well. Symptoms include weak muscles, numbness, trouble walking, nausea, weight loss, irritability, fatigue, and increased heart rate. Treatment may include vitamin B12 supplements.
Mild: Hemoglobin 10.0 g/dL to lower limit of normal. Moderate: Hemoglobin 8.0 to 10.0 g/dL. Severe: Hemoglobin 6.5 to 7.9 g/dL[1] Life-threatening: Hemoglobin less than 6.5 g/dL.
The last stage is iron deficiency anemia. It is characterized by a low hemoglobin concentration with small (microcytic), pale (hypochromic) RBCs. Symptoms include fatigue upon exertion, weakness, headaches, apathy, pallor, poor resistance to cold temperatures, low physical work capacity, and poor immune function.
Eye symptoms of low iron can include a pale coloring of the inside of the lower eyelids. In moderate or severe cases of iron deficiency anemia, the inside layer of the lower eyelid is very pale pink or yellow instead of red. Rather than low iron, one common cause of blurry vision is dry eye.
Iron deficiency anaemia (IDA)
Anaemia is defined by the World Health Organization as a Hb level below 120 g/L in non-pregnant females and 130 g/L in males, which is consistent with the definition of anaemia in the National Blood Authority Patient Blood Management Guidelines.
Severe iron deficiency anaemia may increase your risk of developing complications that affect the heart or lungs, such as an abnormally fast heartbeat (tachycardia) or heart failure, where your heart is unable to pump enough blood around your body at the right pressure.
Weight gain related to iron therapy is a common problem in female patients with iron deficiency anemia. Patients under iron therapy should be counseled in terms of weight gain complication and benefits of diet and followed up serum ferritin and Hgb levels to prevent prolonged iron therapy.
Taking iron supplements or getting iron infusions will not instantly result in weight loss, and should not be used as a weight loss tool.
Pernicious anemia.
Not having enough vitamin B12, or being unable to absorb it, can lead to symptoms such as nerve damage, confusion, dementia, memory loss, depression, nausea, heartburn, weight loss, and a smooth, beefy red tongue.
