They said gilberts syndrome is harmless i have fatuige bad body aches brain fog dizziness. why?

Anything: You can have sleep problems from snoring, apnea, restless legs, poor sleep hygeine, anxiety/depression, napping during the day, night seizures, noises in the neighborhood waking you up, bed bugs, waking up to use the bathroom, acid reflux, allergies, or any number of things. I recommend seeing a doctor to get checked out.

Not from Gilberts: Fatigue, body aches, brain fog and dizziness are non-specific issues that may be due to may reasons, including depression. Try gradually increasing physical activity, a healthy diet rich in fresh fruits and vegetables, whole grains; low in saturated fats, no tobacco in any form and no alcohol. Try this religiously for 3-4 months and if you do not see improvement please consult your doc.
