Since past 6 weeks i have had loss of appetite, lost 5kgs and bloating. Doctors thought it is related to my gall bladder surgery in december 2018. However, my blood tests, liver function test and abdominal ultrasound are all clear. I even had a endoscopy done and it shows chronic superficial gastritis. The GP states that it is not serious and did a Autonomic balance test which shows PNS way higher than SNS. Are these symptoms related to gastric issues or stress. I live abroad and am very confused and worried about my health. I dont smoke, rarely drink and exercise regularly yet have lost a lot of weight. My endoscopy is also clear. Please advise as i Live abroad. Kindly provide clear assistance and no request for consultation.
