Anemia, or a low hemoglobin level in the blood, is often linked to heart disease because the heart has to work harder to pump more blood and oxygen through the body.

When your body isn’t getting enough oxygen due to iron-deficiency anemia, your heart starts to work harder and pump blood faster to make up for it. Over time, this can cause damage to your heart, and if your heart can’t keep up with your body’s demand for oxygen, you can develop heart failure.

Conclusions: While there does not appear to be any single etiology that can be predictive or preventative of mortality for anemic patients, individuals with very low Hb concentrations often do not die quickly. Thus, there appears to be a potential time window where transfusion medicine physicians may intervene.

People also sometimes want to know how low can hemoglobin go before causing death. In general, a hemoglobin less than 6.5 gm/dL is considered life-threatening.

The American Society of Anesthesiologists uses hemoglobin levels of 6 g/dL as the trigger for required transfusion, although more recent data suggest decreased mortality with preanesthetic hemoglobin concentrations of greater than 8 g/dL, particularly in renal transplant patients.

Milk interferes with the body’s ability to absorb iron from food and supplements. Cow’s milk can cause intestines to lose small amounts of blood. When blood is lost, iron is lost with it.

Your body can’t absorb iron. Conditions like celiac disease, ulcerative colitis, or Crohn’s disease can make it harder for your intestines to absorb iron. Surgery such as gastric bypass that removes part of your intestines, and medicines used to lower stomach acid can also affect your body’s ability to absorb iron.

Beetroots Beetroot is one of the best ways to increase haemoglobin levels. It is not only high in iron content, but also folic acid along with potassium and fibre. Drink beetroot juice every day to ensure a healthy blood count.
