Calcium, Benefits deficiency and overdose

 All things about calcium

what is calcium and its history? 

Definition of calcium

Calcium is a chemical element with atomic number 20 and the symbol Ca, it is generally found in teeth and bone which contributes to the formation in association with magnesium and phosphorus. Calcium is the most abundant mineral in our bodies about 1 to 1.2 Kg in adults 99% of this calcium contributes to the strength and formation of bone and teeth. The level of calcium in the blood is kept within very narrow limits. Among its functions, in addition to providing structure and rigidity to the bones, it allows the contractility of the muscles the transmission from the brain nerves to the rest of the body. the circulation of the blood, or the production of hormones and enzymes for different functions of the body.

The history of calcium 

According to history, calcium has been known since a long time, in 1908 isolated calcium has been obtained on its own.
this discovery has been done by the English researcher Sir Humphry Davy he has worked to isolate this mineral element by combining mercury oxide and lime and was done Conducting this experiment using electrolysis adding Duffy mercury oxide to lime which is calcium oxide, then passing the electric current in the mixture, so he got an alloy of mercury and calcium, then heated it hard and obtained the element of calcium. this was the story of calcium.

The great benefits of calcium 

Calcium and weight loss

Yeah, you don't know the substantial role of calcium when it comes to weight loss, given its importance in an entire diet. many studies have been conducted about calcium and its role in weight loss studies have revealed that persons who have between 1300 MG and 1400 per day have less body fat. the more calcium in a fat cell the more it burns due to its significant role in how fat is broken down and stored.
Calcium helps maintain the optimum weight both for males and females. And when calcium is lacking from your diet, the body secretes thyroid hormone, which stimulates the bones to release calcium into the bloodstream, and this maintains the balance.
On the other hand, the thyroid hormone stimulates the production of fats and prevents them from being broken down which may lead to obesity. Therefore, make sure that you are taking the right amount of calcium because obesity has many of the health risks associated with it.

Calcium decreases the risk of type II diabetes 

A study has been conducted by Boston University researchers of approximately 8400 nurses no one of whom has diabetes at the beginning of the study. women who have taken 1200 mg of calcium and 800 IU of vitamin D per day had a 33% lower risk of developing type 2 diabetes than women who consumed much lower amounts.
Not all calcium supplements are equally absorbed. The body absorbs calcium from chewable supplements better than that from tablets. Boston researchers have found that 1,200 mg a day reduces the risk of type 2 diabetes. To improve absorption, take two doses, one in the morning and one in the evening. Calcium has long been considered a relatively inert substance in the body however its display as a second intracellular messenger  (for example for peptide-c) and its electrophysiological potential make it an ion of great importance in dynamic phenomena involving membrane exchange and disturbances of cellular secretions. Which is of great importance in NID diabetes.  

Calcium useful for bone growth and strengthening

Calcium helps protect osteoporosis it is one of the most important and essential nutrients for bone health and growth. especially for young kids from birth to 13 years.
Calcium absorption and bone growth peaks until the age of 20, and gradually decrease thereafter. Adequate amounts of calcium and vitamin D increase bone density in children and infants.
It has been proven that the deficiency of calcium and vitamin D to be related to osteoporosis, vertebral compaction, and even fractures. calcium supplements reduce the risk of these diseases It can then be offered to people with deficiencies, whose diet is naturally low in calcium (vegans, lactose intolerant, allergic to milk proteins). 

Calcium protects the heart 

Sydney ringer was the first one who has begun the research about the relation between calcium and heart protection. Calcium has been proven to have a fundamental and necessary role in the electrical processes that revolve inside the heart as well as the role that relates to the internal muscle fibers of the heart. Studies have shown that a lack of calcium in the blood works to weaken the heart's function.
In order for the heart to send impulses and pump blood to different parts of the body, it must contain a good membrane and the ability to send positive and negative electrical ions regularly, and it has been proven that calcium has a major role in the regulation of the heartbeat, because it works to maintain All cells of the cardiac membrane, which helps to regulate the heartbeat.
When you consume enough calcium it protects the heart muscles and helps them to relax properly.

 Calcium contributes to physical activity and sports 

In addition to its known ability to maintain strong and healthy bones calcium has an essential role when it comes to nerve impulses that lead to muscle cramps. An adequate supply of this mineral can prevent muscle cramps in athletes and endurance athletes. It has been observed that athletes who remove calcium-rich products from their diets and do not supplement them adequately, usually experience changes in muscle cramps and cramps. Re-introducing calcium in their diets greatly reduces their appearance.
Moreover, it has also been observed that calcium supplementation in endurance math not only increases the mineral density in the bones but also helps maintain a small lump (muscle).
 

Other benefits of calcium 

Calcium supplements can help reduce high blood pressure, and it has been observed that people with low calcium intake intend to blood pressure. Calcium has also been shown to help reduce heart failure by regulating muscle contractions.

Moreover, calcium appears to reduce anxiety
by releasing neurotransmitters such as Serotonin and Choline Acetylase, which are responsible for regulating nerve impulses. 

calcium nutritional supplements have been observed to help reduce headaches associated with menopause, irritation, insomnia, and depression.

Calcium deficiency( symptoms)

Osteoporosis  

 Bones contain minerals, including calcium and phosphorous, which make them hard and dense. To maintain bone density (or bone mass), the body needs an adequate supply of calcium and other minerals.
 Calcium deficiency causes weakening and thinning of the bone studies have shown the relation among the two of them alike.
It also makes it very fragile and more likely to be broken or even some minor actions such as bending. spine and wrist are among the most common areas where fractures occur as a result of osteoporosis. 

 The relation between cramps and calcium deficiency 

Muscle cramps are not alarming but if they persist they can hide a chronic and severe calcium deficiency This mineral helps muscles move. When the body does not receive enough, muscle tenderness, contraction, and general discomfort may occur. If you are deficient for a short time, you probably won't have any obvious physical symptoms, but if it becomes chronic, it can cause muscle discomfort or contractions, because calcium is what helps your muscles to function normally. If you notice this sign, frequent muscle cramps, it's a red flag for a severe impairment.

Numbness or tingling 

In the case of calcium deficiency, the muscles and nerves become abnormally excitable. in the early stage of calcium deficiency, numbness or tingling in the fingertips or around the fingers may occur. If you notice involuntary muscle contractions, this can be more serious. There is a test in which a blood pressure cuff is placed on the upper part of the arm and inflated to decrease blood flow to the hand. If it causes hand spasms, it's called the Trousseau sign, something that is present in 94 percent of those with calcium deficiency and that occurs in only 1% of people whose rate calcium is normal.

Calcium deficiency may provoke heart problems

 The heart contains an electrical conduction system that sends signals to the heart muscles that ask them to pump blood to the rest of the body. when there is a deficiency of calcium it can lead to abnormalities in this electrical conduction system, which may lead to abnormal heart rhythms. with an abnormal heartbeat,
you may lose consciousness, or feel your heart beating very quickly. Calcium deficiency can have a negative effect on the heart muscles that contract and pump blood, which may eventually lead to heart failure. so if you maintain a good level of calcium in your body it will contribute to the regulation of the heartbeat.

Dental caries

As you know calcium protects your teeth, many studies have matched dental caries with calcium deficiency. the low calcium in the diet pushes the body to extract it from bones and teeth and this increases the risk of dental caries. 

Dry skin 

where the calcium deficiency in the blood is associated with the occurrence of dryness and itching of the skin, as may increase the risk of developing dermatitis known as eczema, which is accompanied by redness, the appearance of pimples, and itchy skin, and is treated with medications, and the lack of calcium also increases The risk of psoriasis is a skin disease that is difficult to treat, but which can be controlled and controlled.

Anyway, it can cause more or less serious consequences like tremors in the muscles. It is also not uncommon to suffer from tetany which is manifested by significant discomfort, muscles which stiffen then contract and tremors. This deficit can also lead to heart rhythm problems or even heart dysfunction, especially in adults. And when linked to vitamin D deficiency, kidney failure, or even a parathyroid hormone (PTH), it can cause hypokalemia (a decrease in the amount of potassium in the blood). 

Calcium overdose 

Hypercalcemia is often asymptomatic. The first symptoms of hypercalcemia are usually constipation, nausea, vomiting, abdominal pain, and loss of appetite. Diuresis can be abnormally high, which leads to dehydration and increased thirst.
Extremely severe hypercalcemia causes brain disorders with confusion, emotional disturbances, confusion syndrome, hallucinations, and coma. Muscle weakness and possible heart rhythm disturbances can occur.

Severe or severe hypercalcemia often leads to the formation of calcium-containing kidney stones. Kidney failure is rarer and usually disappears with treatment. However, if too much calcium accumulates in the kidneys, the damage cannot be repaired.
 

 How much calcium you should take per day?

The doses of calcium per day

According to studies, these are the best doses for the human body:
babies: 0 to 6 months need 200 milligrams
babies: 7 months to 12 months need 260 milligrams
Kids: 1 year to 3 years need 700 milligrams
Kids: 4 years to 8-year need 1000 milligrams
9 years to 18 years need 1300 milligrams
19 years to 50 years need 1000 milligrams
51 years to 70 years need 1000 for males and 1200 for females
71 years and above 1200 milligrams
Pregnant and breastfeeding women require 1,000–1,300 mg depending on age.   

summary 

 Calcium is one of the most essential and important minerals for the human body it plays a significant role in many vital functions.
Such as teeth and bone protection and muscle heart prevention calcium is also useful for the skin and blood pressure. 
you should take into consideration the recommended doses of calcium because like its deficiency has bad effects the overdose also has bad effects on the human body.
