After a positive FIT test I have had a ct colonography with dye. My results are ok thankfully but due to on going constipation I have been prescribed Laxido, a sachet a day. Since then I have this awful metallic taste in my mouth, it’s constant and waking me up at night. I’ve had recent bloods taken which shows kidney and liver function to be ok. Anyone experienced this? I’m not sure if I should stop the Laxido, I’ve tried most natural foods in my diet but I suffer from hypothyroidism so no foods help.
