This can be gastroesophageal reflux disease or GERD (called as reflux also). This can cause cough on laughing or after the food and incidentally; also very commonly known reason for the night sweats. An upper gastrointestinal endoscopy (camera exam) and a barium swallow (x-ray test) would be able to confirm it. The other possibility can be bronchial asthma and an auscultation by a doctor would diagnose it. The treatment of asthma is by bronchodilator medications, nebulizer and inhalers. The GERD is treated by antacids (Maalox, Tums) and acid blockers (Prilosec, Zantac).
