1, the causes of black stool
The pathological causes of black stool include: upper gastrointestinal bleeding, acute and chronic gastritis, cirrhosis combined with esophageal or fundal varices rupture, gastric cancer, stress ulcers.
Physiologic causes of black stools include: taking black foods (black sesame, black beans, etc.), taking medications that cause black stools (e.g., oral activated charcoal powder, iron supplements that replenish blood, bismuth supplements that treat gastric disorders, and certain traditional Chinese medicines, etc.).
2, iron after the discharge of black stool causes
The main reason why the patient in taking iron after the discharge of black stool is that iron in the gastrointestinal tract will be combined with hydrogen sulfide, which leads to the color of the stool becomes black.
3, iron can not be eaten with food
1, high-fat food can inhibit the secretion of gastric acid, is not conducive to the absorption of iron;
2, tea contains tannin, can be generated with iron and iron intolerance of iron salts, impede the absorption of iron;
3, calcium, phosphorus-containing foods, such as milk, peanut butter can be generated with iron and insoluble substances, affecting the absorption of iron. substances, affecting the absorption of iron.
4, iron supplements black stool how
If it is because of the taking of iron after the black stool does not need to do any special treatment, in the stop taking iron after the black stool will disappear naturally.
Additionally, it is important to note that taking iron can lead to dryness and constipation, so you should eat more high-fiber foods to help relieve constipation.
5, the side effects of taking iron
Long-term use of medication-based iron, the stomach and intestines have a certain stimulus, causing nausea, vomiting, diarrhea, black stools and so on.
It is recommended that patients use some nutritional iron supplements that do not stimulate the stomach and intestines and have a higher absorption rate.
6, dietary taboos
1, should not blindly supplement iron
supplemental iron should be in the arrangement of the experts as well as under the advice of the iron, because iron can treat anemia and malnutrition, some people think that iron is a blood nutrient medicine, so blindly take, this is harmful. Blindly taking iron will produce the following harms, 1) taking too much iron for a long time, excessive iron can be deposited in the tissue cells of many organs in the liver, spleen, thyroid, adrenal glands and stomach, etc., which is common, and can induce cirrhosis of the liver, diabetes mellitus and skin pigmentation, etc., which is known as idiopathic hemoglobinosis. 2) Even if too much iron is ingested at one time, it can corrode the mucous membrane of the stomach and make the free iron in the blood circulation excessive. Excessive free iron in the blood circulation, just like will gastritis become gastric cancer, there will be cellular hypoxia, acidosis, and in severe cases, shock and cardiac insufficiency.3)Normal iron supplementation, if the dose is too large will also have adverse reactions, nausea, vomiting, abdominal pain, diarrhea, bad taste in the mouth, jaundice, drowsiness and so on. Therefore, you can not blindly take iron supplements, such as the condition requires iron supplements, but also to start with a small dose and gradually increase the dose.
2, should not be served at the same time with its drugs
In the use of iron should pay attention to understand, some drugs will affect the absorption of iron, in taking should not be served at the same time with other drugs, 1) should not be served with antacids, these drugs can reduce the concentration of gastric acid, and iron in the form of ferrous iron ions from the intestinal tract to be absorbed, the gastric acid to promote the trivalent iron reduction to divalent iron, which can increase the absorption of iron, antacid Drugs are not conducive to the formation of divalent iron, affecting absorption.2) Should not be taken with alkaline drugs, these drugs encounter iron, can produce insoluble complexes or precipitates, hindering the absorption of iron, and at the same time, alkaline drugs will neutralize the gastric acid, reducing the concentration of gastric acid, affecting the absorption of iron.3) Should not be taken with antimicrobial agents, the formation of iron will be insoluble compounds with some of the components of these antimicrobial agents, affecting the absorption of iron.4) Should not be taken with Lipid-lowering drugs taken with these drugs can combine with iron and reduce absorption, reducing the efficacy of treatment.
3, should not just drink drinks
In taking iron some dairy products and beans can not be consumed. Milk is alkaline food, so that the acidity of the gastric juice is reduced, is not conducive to the dissociation of iron and the formation of divalent iron ions, and milk contains calcium and phosphate, can make iron precipitation, hindering the absorption of iron. Tea contains a large amount of tannic acid, tannic acid is easy to combine with low-valent iron, the formation of insoluble substances, affecting the absorption of iron, and anemic patients drink tea, will make the symptoms of anemia aggravated. Coffee contains some polyphenolic compounds, which can form insoluble salts with iron, hindering iron absorption. Soybean milk is rich in amino acids, diabetes supplement what calcium will react with iron, the formation of chelates that can not be absorbed by the body, affecting the absorption of iron, so take iron should not drink milk, tea, coffee, soybean milk and other beverages.
