### input:
Hi. I am 42 year old fit and healty male, I have been experiencing wheezing during exhalation off and on for the last 12 months. I have had cardiac testing and lung testing and X-rays and all is looking normal. I have also trailed a variety of asthma inhalers without success. My symtoms are fatigue, irritability, bad sleeping, exhausted upon waking, lack of concentration, cannot exhale carbon dioxide efficiently during exercise, headaches.Iatelly the laboured  breathing is becoming more frequent. My latest observation is that the wheezing or restriction may be in the upper throat region. I am no doctor so this may be an incorrect observation.I now fear I may stop breathing while sleeping.Your help would be much appreciated. Jase

### output:

Hello dear, Wheezing is caused due to bronchoconstriction (obstruction of smaller airway passages) which is indicative of Hyper-responsiveness of air passages (seasonal allergy or asthma)Management consists of:1. Stalin inhaler-provide symptomatic relief by causing bronchodilator (dilating the smaller airway passages, relieving the obstruction & increasing airflow to lungs)So, you can use it whenever you are having an acute attack.2. Montelukast preparations- used as a maintenance therapy to relieve symptoms of seasonal allergies & asthma.3. Antihistamines can also be used to provide symptomatic relief.4. Protect yourself from exposure to cold, dust or other allergens. If symptoms still persist, it will be better to consult a Pulmonologist & get a proper physical examination done. So that appropriate management steps could be taken. Wishing you a Good Health. Thanks & take care.
