Lower blood calcium

Lower blood calcium's disease overview

The role of calcium in the body

Calcium is one of the most important minerals for the body. Calcium is involved in muscle contraction, neurotransmitter, hemostasis, and release of the body's hormones.

Stability of calcium levels depends on 3 factors: the amount of calcium is put into the body every day (through eating, drinking foods containing calcium), the absorption of calcium in the intestine and the secretion Calcium in the kidney. As recommended, adult body should be provided about 1000mg of calcium/day, then there will be about 200-400mg of calcium absorbed in the intestine, about 200 mg of calcium being eliminated through bile and digestive fluids, amount The rest of the stool is excreted. In addition, about 200mg of calcium is excreted through the kidney. Up to 99% of the amount of calcium in the body is stored in the bone, only 1% of calcium in the form of free - acts as a buffer system, can be exchanged with extracellular fluid to adjust blood calcium levels when needed Thiet. Normally, blood calcium levels range from 8.8 to 10.4 mg/GL (2.2-2.6 mmol/l)

What is

What is blood calcium?

hypocalcemia , also known as blood sugar calcium is a condition of blood calcium concentration with lower value than normal limits. In accurate, blood calcium is defined when the total serum calcium level is lower than 8.8 mg/dl (2.2 mmol/l) with normal plasma protein conditions, or concentration Calcium ionization below 4.7 mg/dl (1.17mmol/l). Lower blood calcium causes symptoms in children and adults. Rickets, height retardation, or crying at night, sweating, ... are common signs in children with blood calcium deficiency. In adults, the decrease in blood calcium levels can cause osteoporosis, spinal degeneration, ...

Causes of Lower blood calcium's disease

Inadequate calcium: Children in the fast growing period, pregnant women or women who raise children with breast milk are subjects with high calcium demand, if not added A full calcium may occur in blood calcium.

Armor impairment: Reducing PTH hormones leads to hypocalcemia, increased blood phosphorus, can lead to chronic symptoms of blood calcium lower. Thyroidism can be the result of confusion in thyroid surgery.

Lack of vitamin D: The supply of not enough vitamin D or malabsorption is a cause of blood calcium lower. Side effects of some drugs such as Phenobarbital, Rifampicin, ... or less exposed to sunlight can also cause vitamin D metabolic disorders, leading to blood calcium.

Lack of magnesium: Unsatisfied intestines, alcoholism, etc. may be a decrease in blood in the blood. Hypotension of blood magnesia is related to relative lack of PTH and causes symptoms of blood calcium.

Pathology in the kidneys: The renal tubules such as fanconi syndrome, a distance of acidic acidosis can be the cause of calcium loss through the kidneys or reduce vitamin D. Blood calcium may also come from the cause of renal failure, which is the result of damage to the kidney cells that cause a decrease in the synthesis of 1.25 (OH) 2D3 or the kidneys reducing phosphate excretion causing this substance in the blood.

Acute pancreatitis: The pancreatic organization is released with many fat decomposition products, creating chelate with calcium, reducing the level of calcium in the blood.

Lower blood protein: reduce the amount of calcium associated with protein, but the amount of calcium ionization is constant, so there is no symptoms of clinically lower blood calcium hypocalcaemia (fake blood calcium). other causes: bleeding infection, increased calcitonin secretion, increased chelate creation reaction in the vascular lumen, increased blood phosphate, drugs, increased calcium sedimentation outside the pulse, ...

Symptoms of Lower blood calcium's disease

Children with blood calcium may manifest the following symptoms:

Stimulating or sleeping, slow.

Leaving and anorexia.

Increased bone reflexes (Chvostek signs: Type in the face of the face - in front of the outer edge of 2cm, seeing the facial muscles of the same side)

Muscle shrinkage (Trousseau: Roll blood pressure on the arm and pump higher than the systolic blood pressure 20mmHg, keep this pressure level for 3 minutes, Trousseau signs positive when seeing seeing Signs "Hand for birth").

Scrambling, trembling.

Adults, common symptoms include:

Increased tendon reflexes (Chvostek marks).

Mechanical spasm (Trousseau).

Cramps.

Scratch.

Arrhythmia.

Disorders of hands and feet.

Abdominal pain.

depression.

acute blood calcium

Clinically

clinically, acute blood calcium is usually manifested in the form of Tenany. The typical signs of a tetany include: parquet in the lips, tongue, limb head, pedal marks (stretched feet like cycling), body pain, convulsions of facial muscles. Tetany signals a severe condition of blood calcium, when blood calcium levels below 7 (<1.75mmol/l).

In addition, patients may have other dangerous symptoms such as:

Convulsions.

Leaving and anorexia in children.

Mechanical spasm

When there are serious manifestations of acute blood calcium, patients should be taken immediately to medical facilities for timely treatment. If not, there will be dangerous complications such as growth retardation in young children or osteoporosis, bone puree in adults.

People at risk for Lower blood calcium's disease

People with a diet that deficiency calcium or disorders in absorption, metabolism and calcium excretion are the risk objects of blood calcium lower. Risk factors include:

Gastrointestinal disorders.

pancreatitis. kidney failure. liver failure.

Axious disorders.

Lack of vitamin D, Magne deficiency.

Endocrine disorders: parathyroid failure, increased calcitonin secretion, ...

The risk of lowering blood calcium also increases in those with high calcium demand such as babies, pregnant women, ...

Prevention of Lower blood calcium's disease

A diet that provides enough calcium can help reduce the risk of lowering blood calcium. Calcium -rich foods include seafood such as shrimp, crabs, shellfish, squid, ... or milk and dairy products. Only calcium supplements should only be added when the doctor is indicated.

The sunbathing in the morning is also important in the metabolism of vitamin D, minimizing the condition of blood calcium.

Limit alcohol, coffee, salt because they reduce the body's calcium absorption ability.

Diagnostic measures for Lower blood calcium's disease

Testing for blood calcium concentration: This is the most important test to diagnose blood calcium.

Check hair, skin, muscle: can also suggest blood calcium hypocalca on patients.

Psychiatric tests: dementia, hallucinations, confusion, ... may be related to blood calcium hypocalca. Mental examination: Chvostek, Trousseau, convulsions, perceived disorders, ... are manifestations of blood calcium.

Lower blood calcium's disease treatments

How to treat blood calcium?

Hypoxemia, especially blood calcium, does not manifest symptoms that can recover on its own without treatment. The doctor will determine the treatment for patients when diagnosed with blood calcium. Specific treatment is as follows:

Addition of intravenous calcium supplements: indicated for acute blood calcium. Intravenous lines will help restore and replenish the amount of calcium deficiency in the body quickly.

Additional calcium supplements by orally

Monitoring and supervision of the medical team.

Treatment of background disease: For hypocalcemia due to previous disease
