Understanding gastrointestinal issues can be quite complex, especially when symptoms are multifaceted and persistent. Based on your description, it seems you are experiencing a combination of symptoms including abdominal pain, feelings of hunger, nausea, and general malaise. These symptoms can be indicative of several underlying conditions, and it is essential to approach them systematically.

Firstly, the sudden onset of intense hunger, especially if it occurs close to meal times, can be related to several factors. One possibility is that your gastrointestinal tract is not processing food efficiently, leading to a rapid return of hunger signals. This could be due to conditions such as gastritis, peptic ulcers, or even functional gastrointestinal disorders like irritable bowel syndrome (IBS). The left upper abdominal pain you mentioned could be associated with gastritis or inflammation of the stomach lining, which can be exacerbated by certain foods or stress.

The fact that you have been diagnosed with gastroenteritis and have not seen improvement after three days of medication raises concerns about the adequacy of the treatment or the possibility of a different underlying issue. Gastroenteritis typically resolves within a few days, and persistent symptoms may suggest that there is more than just a simple viral or bacterial infection at play.
Your symptoms of nausea and the sensation of wanting to vomit could indicate that your stomach is reacting to something it finds irritating, which could be due to dietary choices, stress, or even an underlying condition such as gastroparesis, where the stomach does not empty properly. Additionally, the coldness and weakness in your extremities could be a sign of dehydration or inadequate nutrition, especially if you are not able to eat comfortably due to your gastrointestinal discomfort.

In terms of diagnostic steps, it would be prudent to consider the following:
1. Comprehensive Blood Tests: These can help assess your overall health, check for signs of infection, inflammation, or nutritional deficiencies.

2. Stool Tests: Given your gastrointestinal symptoms, stool tests can help rule out infections or parasites that might be causing your symptoms.

3. Upper Endoscopy (EGD): If symptoms persist, an upper endoscopy may be warranted to visualize the esophagus, stomach, and duodenum to check for ulcers, inflammation, or other abnormalities.

4. Abdominal Ultrasound or CT Scan: These imaging studies can help assess the organs in your abdomen for any structural issues that might be contributing to your symptoms.

5. Dietary Review: Keeping a food diary to track what you eat and any subsequent symptoms can provide valuable information to your healthcare provider.

6. Referral to a Gastroenterologist: If your symptoms persist despite initial treatment, a specialist can provide a more in-depth evaluation and tailored treatment plan.

In the meantime, consider making dietary adjustments such as eating smaller, more frequent meals, avoiding spicy or fatty foods, and ensuring adequate hydration. Stress management techniques, including mindfulness or relaxation exercises, can also be beneficial, as stress can significantly impact gastrointestinal function.

In conclusion, while your symptoms may initially suggest a straightforward case of gastroenteritis, the persistence and nature of your symptoms warrant a more thorough investigation to rule out other potential gastrointestinal disorders. It is essential to communicate openly with your healthcare provider about your symptoms and any changes you experience, as this will aid in reaching an accurate diagnosis and effective treatment plan.
