Sudden weight loss, especially when it is significant (like losing 10 kilograms or more in a year), can be a cause for concern and warrants a thorough medical evaluation. Given your symptoms of stomach pain, cold sweats, fever, and vomiting, it is essential to approach this situation with caution. Here’s a detailed guide on what medical tests you should consider and the steps you should take.


1. Consult a Primary Care Physician
The first step is to schedule an appointment with a primary care physician (PCP). They can perform an initial assessment, review your medical history, and conduct a physical examination. Your PCP will be able to determine if your symptoms and weight loss are indicative of an underlying medical condition.


2. Potential Medical Specialties
Depending on the findings from your initial consultation, your PCP may refer you to specialists. Here are some specialties that may be relevant:
- Gastroenterology: Since you are experiencing stomach pain and gastrointestinal symptoms, a gastroenterologist can evaluate for conditions such as gastritis, ulcers, or other gastrointestinal disorders.

- Endocrinology: If there is a suspicion of hormonal imbalances (like thyroid issues), an endocrinologist can assess conditions such as hyperthyroidism or diabetes.

- Infectious Disease: If there are signs of infection (like fever and sweating), an infectious disease specialist may be necessary to rule out any systemic infections.

- Oncology: In cases where significant weight loss is unexplained, an oncologist may be consulted to rule out malignancies.


3. Recommended Tests
Your healthcare provider may recommend several tests to investigate the cause of your weight loss and symptoms:
- Blood Tests: A complete blood count (CBC) can check for anemia or signs of infection. Comprehensive metabolic panels (CMP) can assess liver and kidney function, electrolyte levels, and blood glucose levels. Thyroid function tests (TFTs) can evaluate thyroid hormone levels.


- Imaging Studies: Depending on your symptoms, imaging studies such as an abdominal ultrasound or CT scan may be ordered to visualize your organs and identify any abnormalities.

- Endoscopy: If gastrointestinal issues are suspected, an upper endoscopy (EGD) may be performed to directly visualize the esophagus, stomach, and duodenum, and to take biopsies if necessary.

- Stool Tests: These can help identify infections, parasites, or malabsorption issues.


4. Lifestyle and Dietary Considerations
While undergoing medical evaluations, it is also essential to consider your lifestyle and dietary habits. Sudden weight loss can sometimes be attributed to stress, changes in diet, or increased physical activity. Keeping a food diary and noting any changes in your eating habits, stress levels, and physical activity can provide valuable information to your healthcare provider.


5. Follow-Up Care
After the initial tests and evaluations, it is crucial to have follow-up appointments to discuss the results and any necessary treatment plans. Depending on the diagnosis, treatment may involve medication, dietary changes, or further specialized care.


Conclusion
In summary, experiencing sudden weight loss accompanied by gastrointestinal symptoms is a significant health concern that requires prompt medical attention. Start by consulting a primary care physician who can guide you through the necessary evaluations and tests. Early detection and intervention are key to addressing any underlying health issues effectively. Remember to communicate openly with your healthcare provider about all your symptoms and concerns, as this will aid in accurate diagnosis and treatment.
