Introduction

Causes of Malnutrition Malnutrition is a condition where the diet is not balanced resulting with a deficiency disease. It happens worldwide but can be more common to developing countries, as economic, social, cultural and environmental conditions all have an influence Malnutrition is a broad term which refers to both under nutrition and over nutrition. Individuals are malnourished or suffer from under nutrition if their diet does not provide them with sufficient calories and protein for maintenance and growth or they cannot fully utilize the food they eat due to illness. People are malnourished or suffer from over nutrition if they consume too many calories.

Malnutrition commonly occurs when someone does not eat enough food (sub-nutrition). It can also occur if a person has a poor diet that gives them the wrong balance of the basic food groups. It is possible for an obese person whose diet consists mainly of fast food to be malnourished because the type of food they eat lacks the nutrients that their body requires. Malnutrition can be caused by hunger, protein-energy malnutrition and over consumption. People who don't get enough food often experience hunger, and hunger can lead to malnutrition over the long term. But someone can become malnourished for reasons that have nothing to do with hunger. Even people who have plenty to eat may be malnourished if they don't eat food that provides the right nutrients, vitamins, and minerals. ...read more.

Conclusion

Some people become malnourished because they have a disease or condition that prevents them from digesting or absorbing their food properly. For example, someone with celiac disease has intestinal problems that are triggered by a protein called gluten, which is found in wheat, rye, and barley. Celiac disease can interfere with the intestine's ability to absorb nutrients, which may result in nutritional deficiencies. Signs and symptoms of malnutrition Loss of fat, breathing, depression, higher risk of complications after surgery, longer healing times for wounds, poor growth, problems with organ function, learning difficulties, underweight, longer recovery from illness and tiredness. In more severe cases skin may become thin, dry, pale and cold. Hair becomes dry and fall out easily. If lack of calorie continues for long enough, there may be heart and liver failure. ...read more.
