Hi welcome to Health care magic forum.
Thanks for using H.C.M.Forum.
At present you had pain abdomen, vomiting sensation, and loose motions after passing stools, you got relieved of the pain.
Your doubt is whether the throat infection has any relation with the stomach issues. long back you had throat infection, and cleared with out any medicines.It has no relation with the present condition, very rarely with severe pharyngitis may have possibility of getting stomach problem.
You have got a chronic stomach issue with T.G 900+ and using finofibrate.
The present infection is gastroenteritis, and it need to be treated separately. i advise you to consult a physician for diagnosis and treatment. There is possibility of getting pain and motions if untreated.
Wishing For a quick and complete recovery.
Best regards.

Hi,
Thanks for posting your query.
With the available described details, there could also be possibility that you are suffering from acute viral gastroenteritis.
At times throat infection by virus may also involve gastrointestinal tract and may cause gastroenteritis.
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should also go for complete blood count, ultrasound imaging, and serum electrolytes, renal function test.
You should take complete antibiotic therapy, antispasmodics, probiotics, antipyretics, if needed.
You should maintain your hydration status by taking potassium rich liquids.
Take soft diet along with yogurt and banana.
Avoid milk and all milk related products.
You should continue fenofibrates under guidance of your treating doctor.
Take care,
Dr. Mayank Bhargava

Hi ! Throat infection may be related to the abdominal symptoms, but such correlation is more frequent in a child (Paediartric age group).
In your case food poisoning looks to be more appropriate diagnosis depending on your food habits, and if you had any food from outside, which possibly was infected without your knowledge. For this you should get your stool tested and consult your family physician for further management.
Triglycerides in your blood is high and is a matter of concern. Possibly you should think of going for a high roughage diet and more of liquids apart from doing regular exercises. Also I am not sure if you had a cardio vascular assesment or not. If not it is time to go for it with the history of upper abdominal pain and vomiting. Good luck.
