Ferritin is a protein responsible for storing iron within the body. Measuring ferritin levels through a blood test provides important information about the body’s iron reserves.
Iron plays a crucial role in oxygen transport, cellular energy production, and overall metabolic health. When iron stores become depleted, the body may struggle to maintain optimal physiological function.
Low ferritin levels may occur even before iron deficiency anaemia develops. This means that individuals may begin experiencing symptoms before haemoglobin levels fall below normal ranges.
One of the most common symptoms associated with low ferritin levels is fatigue. Iron is necessary for producing haemoglobin, which carries oxygen through red blood cells. When oxygen delivery to tissues becomes less efficient, individuals may feel tired or weak even with normal daily activities.
Low ferritin levels may also contribute to hair thinning or increased hair shedding. Hair follicles require adequate oxygen and nutrient supply to maintain normal growth cycles. When iron stores are low, hair growth may slow and shedding may increase.
Other symptoms associated with low ferritin may include shortness of breath, dizziness, pale skin, headaches, and reduced physical endurance.
There are several potential causes of low ferritin levels. Poor dietary intake of iron is one factor, particularly in individuals following restrictive diets. Increased iron requirements during certain life stages may also contribute to low ferritin levels.
Blood loss, digestive absorption issues, and certain medical conditions may also affect iron stores.
Testing ferritin levels through a blood test can help detect low iron stores early and guide further investigation if necessary. Ferritin testing is commonly included in blood panels used to investigate fatigue, hair loss, or suspected nutrient deficiencies.
Monitoring ferritin levels provides valuable insights into iron metabolism and overall health.
