Your symptoms are present in a wide variety of medical conditions, including tension headaches, benign tremors, or low blood sugar. Keep track of how you are feeling. Has it been a long time since you ate something? If you are concerned about your symptoms, then you should contact your doctor.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Food poisoning is common, but can also be life threatening. The symptoms for food poisoning are fever, abdominal pain, headache, diarrhea, nausea and vomiting. Food poisoning has many causes, for example, chemicals (from toxic fish or plants) and bacteria (Staphylococcus aureus or Salmonella). Treatment of food poisoning depends upon the cause.
Gastritis (acute and chronic) is an inflammation of the lining of the stomach Some people have no gastritis symptoms, but when they do occur they may include bloating, belching, loss of appetite, nausea, and vomiting. H. pylori infection and nonsteroidal anti-inflammatory drugs (NSAIDs) are the two main causes of gastritis. Alcohol, caffeine, and high-fat foods also can cause gastritis. Fried, fatty, and spicy foods, and alcohol aggravate gastritis symptoms. Other stomach lining irritants that aggravate symptoms include cigarette smoking, acidic juices, caffeine, tomato products, peppers, and chili powder. Foods that sooth gastritis symptoms, and that help reduce and stop H. pylori infection growth in the stomach include apples, onions, garlic, teas, green leafy vegetables, coconut water, and wheat bran. Gastritis is diagnosed with endoscopy, blood tests, or stool tests. Some people get relief from gastritis symptoms with prescription and non-prescription antacids, histamine blockers like famotidine (Pepcid AC) or ranitidine (Zantac 75), or proton pump inhibitors (PPIs) like omeprazole (Prilosec) and esomeprazole (Nexium). These drugs will not cure gastritis. Complications of gastritis include gastric cancers, MALT lymphoma, renal problems, and death.
Hepatitis means inflammation of the liver. Hepatitis A (HAV, Hep A) is one type of liver disease caused by a virus. Since hepatitis A is a virus, it can pass from person to person from eating or drinking contaminated food or coming into contact with contaminated materials containing the virus. Symptoms of hepatitis A include stomach pain, diarrhea, dark yellow urine, jaundice, and more. There is a vaccine to prevent contracting hepatitis A.
