I'm a 23-year-old female, around 130 lbs, and I'm really anxious about health stuff recently, especially after reading about various symptoms. A while back, I had the flu with fever, diarrhea, and a low appetite, and though those symptoms are gone, I still feel weak and lightheaded. It got me worried about an electrolyte imbalance. I took two 150 mg doses of fluconazole for a candida infection right after my flu, and I read that's something that could affect potassium levels. Sometimes, I think I'm having heart palpitations, with my resting pulse varying from 59 to 75. It feels like my heart is either pounding or too weak at times. The lightheadedness often kicks in after I walk a lot or panic. I've been trying to up my potassium intake but can't seem to reach the 4700mg target. Do you think this could lead to a significant imbalance or even a cardiac issue?
