Deficiency diseases of vitamins, proteins, calories and Minerals

If the diet containing an inadequate amount of a nutrient is taken for long time deficiency of that nutrient appear at some disorder in body. The deficiency disorder affects the structure and functions of the body parts which depend on that nutrient directly or indirectly this disorder produced by inadequate nutrient in the diet are called deficiency diseases. Deficiency diseases of vitamins

In this article we know about deficiency diseases of vitamins, proteins, calories and Minerals. The excess of nutrient like protein vitamins and minerals in diet is also harmful for the body.

Deficiency disease

The disorder in body produced by inadequate amount of nutrients like protein vitamins minerals in the diet are known as deficiency disease. Deficiency disease is caused by inadequate amount of proteins, calories, vitamins and minerals in the diet. Several types of disease caused due to deficiency of vitamins, deficiency of proteins deficiency of minerals in our body. Deficiency diseases of vitamins

The excess of nutrient in the diet is also harmful for the body. animal fats taken in excess produce cardiovascular disease like disease of heart and blood vessels. large amount of animal protein may cause cancer of large intestine and excess of even some vitamin such as Vitamin A and Vitamin D has an adverse effect on the body.

Deficiency diseases of vitamins, proteins and calories

So the diet should neither have an excess nor deficiency of any nutrients for normal healthy growth of body. Deficiency diseases of vitamins

Deficiency diseases of vitamins

As we know vitamins are organic compound which cannot be produced by the body and must be supplied in a small amount in diet to perform specific biological functions for the normal growth health and maintenance of the body. there are essential to us for proper functioning of different organ.

For proper growth and maintenance of body we have required certain amount of vitamins of several category water soluble vitamins and fat soluble vitamins. Taking of inadequate amount of vitamins in the diet in leads to the situation that is called vitamin deficiency.

As we know vitamins are classified into two category water soluble vitamins and fat soluble vitamins.

The vitamins which are soluble in water is known as water soluble vitamins for example Vitamin B complex vitamin C are water soluble vitamins. the water soluble vitamins are not stored inside our cells, water soluble vitamin must be supplied regularly in diet because they are really excreted in urine and cannot be stored in our body except vitamin B12

Fat soluble vitamins are the vitamins which are soluble in fats are known as fat soluble vitamins. for example vitamin A, vitamin D, vitamin E vitamin K are fat soluble vitamin.

liver cells are rich in fat soluble vitamins such as vitamin A and Vitamin D. this group of hydrophobic lipid soluble vitamin are not absorbed in body and unless fat digestion and absorption process function normally. their deficiency can cause malabsorptive disease related to vitamin deficiency.

Excess intake of fat soluble vitamin causes increase in concentration that situation is known as hypervitaminosis. And condition of hypervitaminosis in our body is mainly caused due to fat soluble vitamin like vitamin A vitamin D vitamin E and Vitamin K

The absence of deficiency of Vitamin can cause a specific disease known as deficiency disease of vitamin. multiple deficiency caused by lack of more than one vitamins are more common in human beings this condition of Vitamins deficiency is known as avitaminosis.

Deficiency diseases for vitamins caused due to inadequate amount of vitamins like vitamin A Vitamin B complex vitamin C vitamin D vitamin E vitamin K in their diet.

Deficiency of Vitamin adversely effects on body growth and development and maintenance of body. Vitamin deficiency disease decrease your immunity. As we know that vitamins are necessary for normal skeletal development of body maintaining proper vision, healthy, teeth, skin and Eyes.

Deficiency disease for vitamin A

Deficiency diseases of vitamins A. As we know that the chemical name of vitamin A is retinal and it is fat soluble vitamin and it is also called bright eye vitamin. and Vitamin A is required for proper growth and normal skeletal development of body and it play important role in maintaining proper vision and essential for healthy teeth structure and it maintenance of healthy glowing soft skin.

And the source of vitamin A is butter, liver, carrots, kidney pumpkin, Mustard leaves, whole milk, liver oil, tomato, coriander leaves, curd, mangoes, egg ,cheese and papaya. Deficiency diseases of vitamins

Vitamin A is present in the form of carotene in vegetables and fruits which are converted to vitamin A in the body. in general the darker the colour of green vegetables greater is there carotene content.

Deficiency disease of vitamin A causes night blindness and xerophthalmia. Now let us discuss deficiency disease of vitamin A night blindness and xerophthalmia in details.

What is night blindness?

Night blindness is caused by deficiency of vitamin A. it is the inability of person to see in dim light. it is due to deficiency of rhodopsin in the rod cells of the retina.it is a type of vision impairment also known as nyctalopia. People with night blindness experience poor vision at night or in dimly lit environments.

Deficiency of Vitamin A disease night blindness

Although the term night blindness implies that you can not see at night, this is not true the case. You may just have more difficulty seeing or driving in darkness.

Some types of night blindness are treatable while other types are not cure. See your doctor to determine the underlying cause of your vision impairment. Once you know the cause of the problem, you can take steps to correct your vision.

Symptoms of night blindness

The main symptom of night blindness is difficulty seeing in the dark. You are more likely to experience night blindness when your eyes transition from a bright environment to an area of low light, such as when you leave a sunny sidewalk to enter a dimly light.

Deficiency of Vitamin A disease cataract

You are also likely to experience poor vision when driving due to the intermittent brightness of headlights and streetlights on the road.

What causes night blindness?

A few eye conditions can cause night blindness are as follows:-

1) nearsightedness, or blurred vision when looking at faraway objects

2) cataracts, or clouding of the eye’s lens

3) retinitis pigmentosa, which occurs when dark pigment collects in your retina and creates tunnel vision

4) Usher syndrome, a genetic condition that affects both hearing and vision

5) Older adults have a greater risk of developing cataracts. They’re therefore more likely to have night blindness due to cataracts than children or young adults.

5) In rare cases in the United States and india or in other parts of the world where nutritional diets may vary, vitamin A deficiency can also lead to night blindness.

Vitamin A, also called retinol, plays a role in transforming nerve impulses into images in the retina. The retina is a light-sensitive area in the back of your eye.

Who are risk of night blindness ?

People who have pancreatic problem such as individuals who suffering from cystic fibrosis, have difficulty absorbing fat and are at a greater risk of having vitamin A deficiency because vitamin A is fat-soluble. This puts them at greater risk for developing night blindness.

People who have high blood glucose sugar levels or diabetes also have a higher risk of developing eye diseases, such as cataracts.

Different treatment options for night blindness?

If your eye doctor will take a detailed medical history and examine your eyes to diagnose night blindness and report. You may also need to give a blood sample. Blood testing can measure your vitamin A and glucose levels.

Night blindness caused due to nearsightedness, cataracts, or vitamin A deficiency is treatable and curable. Corrective lenses of power, such as eyeglasses or contacts, can improve nearsighted vision both during the day and at night.

Let your doctor know if you still have trouble seeing in dim light even with corrective lenses.

Cataracts is also responsible for night blindness

Clouded portions of your eye’s lens are known as cataracts.

Cataracts can be removed through surgery. Your surgeon will replace your cloudy lens with a clear, artificial lens. Your night blindness will improve significantly after surgery if this is the underlying cause.

Vitamin A deficiency

If your vitamin A nutrition levels are low, your doctor might recommend vitamin supplements. Take the supplements exactly as directed.

Most people don’t have vitamin A deficiency because they have access to proper nutrition.

Genetic conditions

Genetic conditions that cause night blindness, such as retinitis pigmentosa, are not treatable. The gene that causes pigment to build up in the retina does not respond to corrective lenses or surgery.

People who have cataract retinitis pigmentosa of night blindness should avoid driving at night.

How can I prevent night blindness?

You can’t prevent night blindness that’s the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar levels and eat a balanced diet to make night blindness less likely.

Eat foods rich in antioxidants, vitamins, and minerals, which may help prevent cataracts. Also, choose foods that contain high levels of vitamin A to reduce your risk of night blindness.

Certain orange-colored foods are excellent sources of vitamin A
butter, liver, carrots, kidney pumpkin, Mustard leaves, whole milk, liver oil, tomato, coriander leaves, curd, mangoes, egg ,cheese and papaya.
