As an indication, <strong>normal haemoglobin values are<\/strong> as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Men:<\/strong> 13.4 &#8211; 17.5 g\/dL<\/li><li><strong>Women:<\/strong> 12 &#8211; 15.5 g\/dL<\/li><li><strong>Pregnant women:<\/strong> \u2265 11 g\/dL<\/li><\/ul>\n\n\n\n<p>The <strong>average haemoglobin values in children and adolescents<\/strong> are (depending on age and gender) as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Birth:<\/strong> average 16.5 g\/dL<\/li><li><strong>First month:<\/strong> average 14.0 g\/dL<\/li><li><strong>2 months:<\/strong> average 11.5 g\/dL<\/li><li><strong>3-6 months:<\/strong> average 11.5 g\/dL<\/li><li><strong>From 6 months to 2 years:<\/strong> average 12.0 g\/dL<\/li><li><strong>2-6 years:<\/strong> average 12.5 g\/dL<\/li><li><strong>6-12 years:<\/strong> average 13.5 g\/dL<\/li><li><strong>12-18 year old girls:<\/strong> average 14.0 g\/dL<\/li><li><strong>12-18 year old boys:<\/strong> average 14.5 g\/dL<\/li><\/ul>\n\n\n\n<p>Lower than normal haemoglobin values result in a reduced ability to transport oxygen by <strong>erythrocytes <\/strong>(red blood cells).\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Low Haemoglobin and sport<\/strong><\/h2>\n\n\n\n<p>Low haemoglobin levels may sometimes be measured in sportsmen and sportswomen as a result of intense and prolonged physical exertion.<strong> <\/strong>It is an adaptation of the body in response to increased energy and oxygen consumption during physical exertion. The <strong>haemoglobin and haematocrit levels may be lower <\/strong>as aerobic activity causes an increase in blood volume and consequently a reduction in red blood cell concentration.\u00a0<\/p>\n\n\n\n<p>It is possible to detect low level for haemoglobin and haematocrit in athletes who practice constant physical activity and it is a condition that usually is not a cause for concern. It is different when this condition overlaps with an <strong><a href=\"https:\/\/www.sideral.it\/en\/when-it-is-used\/iron-deficiency\/\">iron deficiency<\/a><\/strong>. In the case of an <strong>iron deficiency<\/strong>, the body may already be struggling to <strong>maintain normal haemoglobin levels<\/strong> and physical activity may worsen the situation.\u00a0<\/p>\n\n\n\n<p>For those who practice <strong>endurance training<\/strong>, foot <strong>race, marathon<\/strong>, <strong>triathlon<\/strong> or <strong>other sports<\/strong> that involve prolonged physical activity, haemoglobin and haematocrit levels may decrease rapidly due to increased intravascular haemolysis. Athletes who practise sports that require significant and prolonged physical exertion may also be subject to micro-traumas that cause micro-bleeding which, in the long run, can affect the balance of iron and haemoglobin in the blood.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How do you overcome iron deficiency by acting on the causes?<\/strong><\/h2>\n\n\n\n<p>When facing <strong>iron deficiency<\/strong>, the doctor generally may suggest an approach that includes a <strong><a href=\"https:\/\/www.sideral.it\/en\/which-foods-are-rich-in-iron-lets-find-out-with-the-iron-rich-food-table\/\">diet with iron-rich foods<\/a><\/strong> and eventually the use of <strong>food supplements<\/strong> or <strong>drugs containing<\/strong> iron. With an <strong>iron deficiency, <\/strong>there can sometimes also be a <strong>deficiency of vitamin B<sub>12<\/sub>: <\/strong>in these cases, the doctor will provide a diet rich in foods that also contain vitamin B<sub>12<\/sub>, such as meat, eggs, fish, soy and cereals.\u00a0<\/p>\n\n\n\n<p>Under normal health conditions, a <strong><a href=\"https:\/\/www.sideral.it\/en\/advice-diet\/\">healthy and balanced diet<\/a><\/strong> is sufficient to keep iron values within the normal range. However, specific physiological conditions (pregnancy, breastfeeding, menstrual cycle) or pathological conditions (diseases that decrease <strong><a href=\"https:\/\/www.sideral.it\/en\/when-it-is-used\/iron-absorption\/\">iron absorption<\/a><\/strong> in the intestine) may cause an <strong>iron deficiency<\/strong> or <strong>an increased need for this nutrient<\/strong>. In these cases, the doctor will assess the best diet to balance the iron deficiency and will consider whether to recommend a <strong>dietary supplement<\/strong> to compensate for the iron deficiency or increased iron demand by the body.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Agonistic athletes may be subject to iron and haemoglobin level below normal range.
