What causes palpitations, fatigue and confusion?
Patient: So I ve been experiencing palpitations, confusion & fatigue for a while now, I thought It was because of iron deficiency but I ve overcome that according to doctor, he said that my liver function levels were slightly abnormal as I had a GGT of 34 when range was 30, I also had slight increase in bilirubin and albumin, I have never had alcohol and am active on most weekends, I m 19 years old and very skinny (have always been skinny), I was very sporty and athletic when I was younger, I also always experience weird feeling as if something is always in my neck. The biggest issue is the palpitations as they re really annoying and I ve also experienced them for a while, any idea with whats wrong with me as I m very very concerned Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  I passed carefully through your question and would explain that palpitations could be related to many situations: anxiety, physical activity, anemia, thyroid gland dysfunction, electrolyte imbalance, etc. Coming to this point, I would recommend checking your thyroid hormone levels and performing a cardiac ultrasound and an ambulatory 24-48 hours ECG monitoring in order to investigate for possible cardiac arrhythmia. If all the above tests result normal, you should consider anxiety as the main cause of palpitations. Regarding high GGT, I would recommend repeating this test after a week just to be sure that it is OK. An abdominal ultrasound for gallbladder stones may be needed.   Hope I have answered your query. Let me know if I can assist you further.
