Home remedies for a chronic cough include quitting smoking and avoiding substances that trigger nasal allergies, states Mayo Clinic. Eating smaller portions several times a day may aid in counteracting a chronic cough that results from acid reflux.
Raising the head while sleeping, and waiting for at least four hours after eating before lying down, may treat a chronic cough that occurs due to acid reflux, explains Mayo Clinic. Medications, such as antibiotics, decongestants, asthma drugs and drugs that counter physiological effects of histamine, may help if home remedies fail to reverse the problem. Patients require medical tests, such as CT scans and X-rays, before undertaking treatment.
Causes include gastroesophageal reflux disease and postnasal drip syndrome, a condition in which there is excessive production of mucus that accumulates at the back of the throat, reports Mayo Clinic. Other conditions that may cause the problem are asthma; medications that treat hypertension and heart failure; and infections, such as pneumonia. Being female and smoking increase the chances of developing a chronic cough.
Signs and symptoms that can accompany a chronic cough include a runny nose, shortness of breath, wheezing and sinus congestion, according to Mayo Clinic. A person who coughs up blood or experiences a cough that lasts for a long period should consult with a doctor. Dizziness, headache and involuntary leakage of urine are possible complications.
