Can this constant hunger be cause by quetiapine?
I have bipolar disorder and have been on some kind of antipsychotic for the past 18 years or so. Currently am on lamotrigine 100mg in the morning + 150g at night + quetiapine 250mg (immediate release) at night.
For over a decade I've had pangs of hunger where I just feel very weak, my hands are shaking and everything falls off of them including the food I'm trying to eat, I trip on everything, can't remember basic words like chair, TV, fridge. It's not cravings - I'm not thinking about any food in particular I'm just weak and crummy and either I eat everything in sight or I eat some candy and even then it takes a bit before I feel like myself again. Once I even had to call my boyfriend to come pick me up because I was on the street and then I could barely walk and just sat on the sidewalk crying.
Some months ago I made an effort to add more fruit and veggies to my diet hoping it will help me feel satiated for longer. And strength training at the gym 2 times a week + one cardio day. But it's not working. I'm still hungry every 1.5hr/2hrs. I'm gaining weight because I'm simply eating more food and my clothes are starting to not fit because I'm adding muscle on top of my normal weight.
When I try ignoring the hunger I get to that point where I'm weak and shaky, my brain can't function and I eat everything in sight.
My current diet is more or less like this:
- Breakfast: 2 scrambled eggs + one small (around 40g) piece of toast + 1 drinkable low fact lactose free yogurt + 1 coffee with a small coffee spoon of sugar.
I'm hungry 1.5hrs (sometimes 1 hr) after this. I eat an apple (peel on) + 30g of cornflakes or 1 drinkable yogurt or 1 solid yogurt (both low fat), sometimes I eat all of this.
- Lunch: always start with a bowl of vegetable soup. Then my plate is about one third vegetables (steamed broccoli/brussel sprouts/green beans/cabbage) + one third protein + one third carb
Once again I'm hungry 1hr - 2hrs after this. I eat a 100g bowl of low fat greek yogurt with 11g all bran cereal + an apple or a liquid yogurt. Sometimes I'm still weak so I eat one toast with scrambled eggs or cornflakes.
- Dinner: same as lunch. And then I need to eat around 30mins before bedtime or else I wake in the middle of the night feeling weak and hungry or wake up in the morning so weak I struggle to get out of bed. I usually eat some cereal + a yogurt or some toast with scrambled egg or greek yogurt with all bran. If I eat soup or fruit I wake up in the middle of the night needing to poop.
I've tried bigger meals (more veggies + side salad of lettuce and tomatoes with a spritz of olive oil and I eat until my stomach is so full it's uncomfortable) but I'm still hungry about 3hrs after. I always have a 700ml bottle of water with me and I'm drinking at least 3 bottles of those per day. Drink alcohol 2 - 4 times per month max and it's always just a glass of sangria or a small bottle of apple cider.
Could it be the quetiapine causing this? My psychiatrist thinks it's not likely. Anyone been through the same?
Edit to add: I'm at a normal weight (154cms and 56kg)but I've spent the past 6 years trying to go down to 50kg with no success, plus, the hunger pangs are just very uncomfortable, especially when they happen when I'm out of the house
