Calcium is crucial
to bone health

How does calcium work?

Calcium is an important mineral for maintaining strong bones and teeth. In fact, it gives strength to the entire skeletal system. Calcium also ensures the smooth functioning of nerves and muscles, and plays an important role in the transport of substances throughout the body.

Vitamin D is required to help the body absorb calcium properly. It is vital that the body maintains a healthy ratio between calcium and phosphorus.

Calcium in the diet

Important sources of calcium include cheese, milk and dairy products. Moreover, the consumption of potatoes, vegetables, nuts and legumes helps to provide a proper intake of calcium for the body.

Calcium deficiency

A calcium deficiency can cause the onset of osteoporosis (bone decalcification). The bones become more fragile and risk increases that they may break more easily. Calcium deficiency, combined with the lack of vitamin D may give rise to osteomalacia (weakening of the bones). In some subjects a calcium deficiency can cause a slowing of the normal process of blood clotting.

Excess calcium

An excess of calcium occurs if the amount of calcium taken daily is greater than 2500 mg. In this case the calcium hinders the absorption of other minerals such as iron, zinc, magnesium and phosphorus. It also increases the risk of developing kidney stones and bone formation, rather than being stimulated, is actually weakened.

Calcium and weight loss surgery

Following surgery for weight loss, the rapid decline in body weight changes the pressure that the bone structure is normally subject to. The weight reduction inhibits bone formation compared to the period prior to surgery. The bone structure will also take on less calcium, due to the reduced absorption of vitamin D. To overcome the lack of calcium the body reacts by steadily chipping away at the calcium in the skeleton.

Following the placement of a gastric band or sleeve

For people who have recently undergone surgery for a gastric band or sleeve procedure, the recommended daily allowance is close to 150%. A daily intake of calcium in the region of 1200 mg is recommended.

Following gastric bypass surgery, duodenal switch or biliopancreatic diversion procedures

For anyone who has undergone gastric bypass, duodenal switch or biliopancreatic procedures, the recommended daily allowance (RDA) is between 150 and 300%. The reason lies in the fact that, due to recent weight loss surgery, the nutrients do not pass along all of the small intestine, which would normally occur when the body absorbs calcium under normal circumstances.
