I started feeling very fatigued two days ago, after 1 or 2

Resolved Question:

I started feeling very fatigued two days ago, after 1 or 2 hours of exposure to the sun abroad.

Symptoms initially were: dizziness, fatigue, slight constipation, slight unconsciousness and sometimes shivering.

I drunk more and the symptoms seemed to improve until yesterday when I drunk a coffee.

After few hours the symptoms were: extreme fatigue, weakness, hot skin, slight diarrea, nausea, shallow and fatigued breath.

This morning, 14 hours after the coffee, the symptoms persist and I still feel extremely tired and the skin is hot.

Can it be adrenal insufficiency? What should I do?

It happened in the past to feel weaker or fatigued after coffees or sugar consumption. But I'm not sure it's a digestive related issue, having been diagnosed with both gastritis and IBS.

What should I do, considered that I should leave London for Liverpool right now with the train. Should I seek medical assistence there? Should I check the blood pressure? What should I check?

Hello. I'm Dr. Phil, licensed and practicing internist. Excellent service is my goal.

Hi there.

Do you still need help on this one?
Customer: replied 3 years ago.

Yes, I still have symptoms. They now sounds more similar to what I had other times by drinking coffees. I still feel fatigued 24 hours after that coffee. In the past, that has been associated to IBS.


But everything has started Friday after exposure to the sun. So I'm a little confused about the cause of my problems.


Are they simply two different problems, IBS and dehydration?


Or is it possible there is an adrenal insufficiency?


Or what else?

I felt better only today, after three days. Can the heat stroke last so long?

Expert:  Dr. Phil, MD replied 3 years ago.
Absolutely if it caused electrolyte or kidney issues
Customer: replied 3 years ago.

Does it mean I may have problem with my kidney? Or this can happen to anyone?
