###Human: Is it harmful to take Lithium for bipolar disorder with fasting and paleo diet? ###Assistant: Hi. See, Lithium can be harmful if hydration is not well maintained. In such cases, we recommend to increase the amount of fluid. That is to consume a good quantity of fluid in the morning before your fast starts and to drink fluids once you open your fast in the evening, and continue till the next morning. Take Lithium tablets along with two glasses of water each time. Do not go for the Keto diet. You should take a proper balanced diet. Avoid taking a high protein diet. So usually in auspicious month, the fasting duration is for 12 hours. In the remaining 12 hours, keep on taking fluids to compensate. There is no indication to stop or reduce the dosage of Lithium during Ramadan. I hope this helps.
