A nutritional imbalance can be caused by having a deficiency of certain nutrients, such as carbohydrates, protein, fats, vitamins or minerals, according to Mayo Clinic. It can also be the result of having an excess of any of these nutrients as well. Some examples of nutritional imbalances are hypercalcemia, hypervitaminosis A and deficiencies in either vitamin B1 or iron.
People can have nutritional imbalances due to either insufficient or excess amounts of a specific nutrient. Some others may have trouble absorbing these nutrients through diet, which also leads to an imbalance.
Hypercalcemia is an example of having an imbalance due to an excess of calcium in the blood. Although an underlying condition, such as an overactive parathyroid gland, can cause this imbalance, it also may occur due to taking an excess quantity of the mineral calcium or vitamin D supplements, states Mayo Clinic. Likewise, when someone takes an excessive amount of vitamin A, hypervitaminosis A can develop. Vitamin A is a fat-soluble nutrient, and the liver stores excess amounts of it. For this reason, high levels of this vitamin in the body can lead to toxicity and possible liver damage, reports the National Institutes of Health's Office of Dietary Supplements.
Deficiencies in vitamin B1 or thiamine can lead to the condition called beri-beri. Similarly, a serious deficiency in the mineral iron can lead to anemia. Most deficiencies may be the result of poor nutrition. Other deficiencies can develop if the body is not getting enough of the macronutrients, such as protein, carbohydrates and fats, through diet, which are. To avoid nutritional imbalances, people should take the recommended daily allowance specified for each of these nutrients.
