Background: Medication is currently the mainstay of asthma management. Nonetheless, non-pharmacological methods have advanced recently. These methods include breathing exercises, particularly the Buteyko Breathing Technique, which aims to stabilize the irregular breathing patterns that may aggravate asthmatic patients' breathing issues. Aim: To Evaluate the effect of of Buteyko Breathing Technique in Enhancing Asthma Control and Life Quality Among Asthma Patients. Design and setting: A quasi-experimental research design was utilized, involving 60 male and female patients in the chest diseases department and outpatient clinic of the Main University Hospital, Alexandria, Egypt. Tools: Three tools were used for data collection, Biosociodemographic data structured questionnaire, the Asthma Control Test (ACT) and Asthma Quality of Life Questionnaire Standardized Activities. AQLQ (S). Results: Most participants in both groups had poorly managed asthma, with 93.3% in the study group and 90% in the control group. However, following the intervention, the study group demonstrated significant improvement, with the percentage of poorly controlled cases decreasing to 56.7%, while the control group saw minimal change at 93.3%. All participants in both groups were categorized as having a low quality of life. However, after the intervention, the study group experienced a notable shift, with none of the participants remaining in the low category. Instead, 76.7% moved to the moderate QoL category, and 23.3% to the high QoL category. This change was statistically significant (p<0.001). Conclusions, The study's findings indicate that including the Buteyko Breathing Technique in an asthma patient's treatment protocol could improve their control of asthma symptoms and enhance their overall quality of life. As a safe and cost-effective method to alleviate asthma symptoms and enhance quality of life, asthma patients must have access to BBT alongside traditional therapies.
