Severe hypoglycemia: Dizziness, fatigue, weakness, headaches, inability to concentrate, confusion, slurred speech, blurred vision, seizures, and coma. Hypoglycemia symptoms rarely develop until the level of glucose in the blood falls below 60 mg/dL (3.3 mmol/L). Some people develop symptoms at slightly higher levels, especially when blood Description. Hereditary fructose intolerance is a condition that affects a person's ability to digest the sugar fructose. Fructose is a simple sugar found primarily in fruits. Affected individuals develop signs and symptoms of the disorder in infancy when fruits, juices, or other foods containing fructose are introduced into the diet. Nutritional deficiency | Find, read and cite all the research you need on ResearchGate carbohydrates, proteins, and fats, are required in large Trace elements e signs and symptoms of de People with riboflavin deficiency typically have deficiencies of other nutrients, so some of these signs and symptoms might reflect these other deficiencies. Severe riboflavin deficiency can impair the metabolism of other nutrients, especially other B vitamins, through diminished levels of flavin coenzymes [ 3 ]. Signs and symptoms of SAD may include: Feeling listless, sad or down most of the day, nearly every day. Losing interest in activities you once enjoyed. Having low energy and feeling sluggish. Having problems with sleeping too much. Experiencing carbohydrate cravings, overeating and weight gain. Having difficulty concentrating. In a more recent study including 90 selected patients with non-specific abdominal complaints, we observed a high rate of carbohydrate malabsorption (lactose 34%, fructose 61%, and sorbitol 91%) [ 42 ]. After dietary information had been provided, the patients reported significant improvement in 75% of cases, depending on the extent of compliance. Glycogen storage disease (GSD) is a rare condition that changes the way the body uses and stores glycogen, a form of sugar or glucose. Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. Sucrose intolerance. Sucrose intolerance or genetic sucrase-isomaltase deficiency (GSID) is the condition in which sucrase-isomaltase, an enzyme needed for proper metabolism of sucrose (sugar) and starch (e.g., grains), is not produced or the enzyme produced is either partially functional or non-functional in the small intestine. 2. Carbohydrate metabolism. The carbohydrates present in foods are primarily as polysaccharides that are digested by various digestive enzymes. Starch is the most common polysaccharide in foods and is metabolized to maltose by the enzyme alpha amylase present in saliva and secreted by the pancreas and this to glucose by the maltases in the microvilli of the duodenum. Anemia is a condition in which the number of red blood cells may be inadequate or the cells may be abnormal in size or color. There may be multiple causes, including excessive blood loss, cell destruction, or improper cell formation. Several trace mineral deficiencies can result in anemia. PE1QyO.
