Detailed Answer:
Hello,
Thanks for choosing HealthcareMagic for your query.
Have gone through your details and i appreciate your concern.
Normal stools can vary in shades of brown.Mild change in texture can be due to antibiotics you were on.Antibiotic given in paricarditis usually effect our gastro intestinal system however on a serious note Beige or light yellow stool is indicative of problem in hepatobiliary system.Usually its the bile salt which gives color to stool but in case drainage of bile is blocked or liver is producing less bile color of stool become pale.
So my advice is don't panic but To be on safe side i would recommend you to go for Ultrasound abdomen to rule out any problem with hepatobiliary system.If that is normal then change in color can be most likely due to antibiotic therapy you were on or is related to food you are having.
