Hi dear...you are alright...stress and worry can lead to both.. either
diarrhoea or
constipation.
I hope you have your blood pressure regularly ,ECG, thyroid and sugar levels checked annually.Does any one else in your household, workplace , or neighbourhood have this kind of diarrhoea. Eight weeks is a long time... you must have lost lot of electrolytes too.
Do get a
complete blood count / profile, cardiac profile.. ecg a& echo, urea and
creatinine, uric acid, sodium and potassium levels,b12,thyroid function test and HIV, HAV , HEV tests done.If all these are normal may be an ultasound abdomen.
These tests are to find out the cause of diarrhoea.
I hope you will get these investigations done.
Meantime keep yourself hydrated with electrolytes and cereal water.
Have
soft diet that will not cause you to cramp in tummy.
If you continue to lose fluids you will lose electrolytes which can cause secondary conditions of inconvenience to you.
I hope this answers your qusetion dear.
Take care.
