Shortness of breath, also called dyspnea, refers to a feeling of suffocation or an inability or difficulty in breathing. Most commonly, breathing difficulties are reported at high altitudes, but depending on the physical and physiological condition of an individual, it may also occur while climbing stairs, walking, running and, in severe cases, standing for a long time. It can happen suddenly or develop gradually over weeks to months. Shortness of breath primarily occurs due to problems related to the heart or lungs. These organs are responsible for supplying the body with oxygen and removing carbon dioxide from tissues and blood. Any imbalance in the levels of oxygen, carbon dioxide and haemoglobin directly impact the normal functioning of body. Common conditions that cause shortness of breath are asthma, chronic obstructive pulmonary disease, allergic reactions, low blood pressure, anaemia, enlarged heart, coronary heart disease, and choking.
Homeopathic texts describe several remedies for treating conditions that lead to shortness of breath. Medicines such as blatta orientalis, ipecacuanha, lobelia inflata and antimonium tartaricum, are carefully matched with symptoms and personality of the individual and then prescribed to achieve an overall improvement in health.
