<s>[INST] Dear Sir, dear Madam, This afternoon, I started to feel faint from what I believe to be overheating. I felt nauseous, sleepy with a subsequent headache. Afterwards, I even developed an attack of diarrhea. I have suffered from overheating in the past so I recognize the symptoms but diarrhea didn t occur back then. That s why I would like to know whether this might be a normal symptom which will eventually dissappear or I should consult a physician. [/INST] dear,I am suspecting condition of related to infection. Mostly gastric in nature.The symptoms resemble the syndrome commonly associated with infection.I suggest you to see a local physician as antibiotics may be required.regards </s>
