I have lpr and currently taking 40mg nexium a day, modified diet, still have symptoms, 20 years old. am i likely to die young from this?

LPR: If overweight, lose weight. No alcohol, smoking, caffeine, peppermint, spicy foods, having meals less than four hours prior to sleep. LPR does not kill however can have vocal symptoms, cough, chronic throat clearing , feeling of lump. If chronic throat clearing, stop. train self to swallow instead of clearing throat as clearing creates more secretions which then makes one clear threat again, again
