दस्त से होने वाले निर्जलीकरण में ORS प्रभावी क्यों होता है?

Last Updated:

This question tests a core concept of human nutrition: ORS works through sodium–glucose cotransport in the small intestine, allowing sodium and water to be absorbed even during many diarrhoeal illnesses.

Aग्लूकोज आँत में सोडियम और जल के अवशोषण को बढ़ाता है
Bयह आँत की गति पूरी तरह रोक देता है
Cइसमें एंटीबायोटिक होते हैं
Dयह रक्त कोशिकाएँ बदल देता है
Correct Answer: ग्लूकोज आँत में सोडियम और जल के अवशोषण को बढ़ाता हैYour Answer: A

Explanation

सही उत्तर: ग्लूकोज आँत में सोडियम और जल के अवशोषण को बढ़ाता है। ORS छोटी आँत के sodium–glucose cotransport से कार्य करता है, जिससे दस्त के दौरान भी सोडियम और जल का अवशोषण होता है। ग्लूकोज और electrolytes का सही अनुपात जरूरी है; बहुत मीठे गाढ़े पेय osmotic diarrhoea बढ़ा सकते हैं। ORS आँत की गति बंद नहीं करता, सामान्यतः antibiotic नहीं रखता और रक्त कोशिकाएँ नहीं बदलता। अन्य विकल्प पोषण से संबंधित अवश्य हैं, लेकिन वे अलग पोषक तत्व, अलग कार्य, अलग ऊर्जा-मूल्य या अलग कमी-रोग को दर्शाते हैं।

Common questions and clear answers for this topic.

What are the major nutrients required by the human body?

The human body requires six major nutrients: carbohydrates (energy source), proteins (growth and repair), fats (energy storage and insulation), vitamins (regulatory functions), minerals (bone and metabolic functions), and water. Each nutrient plays a specific role in maintaining health. A balanced diet includes all these nutrients in proper proportions.

What are vitamins and what is their role in the body?

Vitamins are organic compounds required in small quantities for normal body function. They are classified as fat-soluble (A, D, E, K) and water-soluble (B-complex, C). Vitamin A maintains vision, D helps calcium absorption, C builds immunity and prevents scurvy, B1 (thiamine) prevents beriberi, and B12 is essential for nerve function and blood formation.

What are deficiency diseases caused by lack of nutrients?

Nutrient deficiency diseases include: Scurvy (Vitamin C deficiency), Rickets (Vitamin D deficiency in children), Beriberi (Vitamin B1/thiamine), Night blindness (Vitamin A), Anaemia (Iron or B12 deficiency), Goitre (Iodine deficiency), Kwashiorkor and Marasmus (protein-energy malnutrition), and Pellagra (Niacin/Vitamin B3 deficiency).

What is the difference between carbohydrates, proteins and fats?

Carbohydrates provide immediate energy (4 kcal/g) and are found in rice, wheat, and fruits. Proteins are building blocks made of amino acids (4 kcal/g), essential for growth and repair, found in eggs, meat, legumes. Fats store energy (9 kcal/g), insulate organs, and aid vitamin absorption; found in oils, butter, nuts.

What is a balanced diet and why is it important?

A balanced diet contains all essential nutrients — carbohydrates, proteins, fats, vitamins, minerals, and water — in the right proportions. It supports growth, maintains energy, boosts immunity, and prevents deficiency diseases. ICMR recommends a daily intake that includes cereals, pulses, vegetables, fruits, dairy, and adequate water.
