Your child could be severely allergic to a particular food item. Can you think of anything that was common in these 2 events. It could be egg, any sea food, any frozen snack, any new food item, some jelly/candy. Such severe bout of vomiting could also result from gastric infection. During such bouts, the body tends to reject anything that is taken orally including water which is why the vomiting continues and situation improves after the fluids and medication is given intravenously. Please think carefully and note down everything that she took in the last 48 hours before she started having vomiting. You might figure out the cause. Take care.

Stomach Ulcers - 5 Ways It Can Be Treated!

A stomach ulcer or gastric ulcer refers to the defects or breakdown in the mucosal lining in the stomach. The stomach contains acid, which helps in digestion and any break in the tissue lining may result in severe pain or bleeding in some cases. The pain is usually felt in the abdomen.

Stomach ulcers cause great discomfort and should be treated effectively. Here are the primary ways for treating stomach ulcers:

  1. Antibiotics: In the case of H. pylori infection, you should take a course of more than two antibiotics, to be taken twice a day and must be continued for a week. Antibiotics such as amoxicillin, clarithromycin or metronidazole may be used in case of such stomach ulcers. However it is always recommended to consult a specialized doctor before consuming any of these medicines. After several weeks of using the antibiotics, you should get a test done for detection of H. pylori bacteria. If they are still present, you have to take different antibiotics.

  2. Proton Pump Inhibitors: Proton pump inhibitors or PPIs helps in the reduction of the amount of acid produced by the stomach. This prevents damage to the ulcer and lets it heal naturally. PPIs are generally taken for four to eight weeks. The most common PPIs which are used for treating stomach ulcers are omeprazole, pantoprazole and lansoprazole.

  3. H2 Receptor Antagonists: H2 receptor antagonists reduce the production of stomach acid and function the same as PPIs. The most common H2 receptor for treating stomach ulcers is ranitidine.

  4. Antacids/ Alginate: All measures to treat stomach ulcers take several hours to show results. Your doctor may prescribe antacid medications for neutralizing the stomach acid. This will provide relief for the moment, but the relief is quite temporary and for a short span of time. By this time, the strong medicines most likely start working. There is a certain antacid medicine known as alginate. This develops a protective coating on the stomach lining. Antacids are available at all over the counter medicine stores and you should consult your doctor to get the best antacid which would work effectively on your stomach ulcer symptoms. You should take antacids before going to sleep or after taking meals.

  5. Natural Remedies: Stomach ulcer can also be treated at home using natural remedies. Medicines may sometimes cause further digestive complications, so home remedies are much more easy to follow and do not have side effects. The best way is to follow a proper diet, which is comprised of certain food items that help in curing stomach ulcers. You should consume bananas, honey, garlic, green leafy vegetables like cabbage, licorice and capsaicin.

Stomach ulcers cause great pain and also bleeding in several cases. Proper treatment procedures should be taken in case of stomach ulcer. There are many medical remedies, as well as home remedies for treating stomach ulcers. If you wish to discuss about any specific problem, you can consult a Gastroenterologist.
