Hi,
Noted the history of pain in abdomen,
constipation, light headedness,
tiredness,
thyroid and iron levels being normal.
yes, you should consult your GP again to have clinical evaluation, examination and further investigations along with symptomatic treatment to start with.
X-ray of abdomen to see for colon and intestinal problems to start with.
Tests of stool and blood.
Ultrasonography of abdomen.
Blood tests for other causes like
typhoid and so on.
All these will lead to a proper diagnosis and gives a plan for proper management.
Till then you can take stool softeners.
Multivitamins with minerals to cope up with weakness.
If the blood sugar is normal then oral rehydration solution may help.
Further management as per the findings.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
