You have excess phlegm produced in throat and breath deeply due to less expansion of lungs?

It sounds like you may be experiencing symptoms of asthma or another respiratory condition. If you are having difficulty breathing, it is important to see a doctor right away.

Here are some tips that may help to reduce phlegm production and improve lung expansion:

- Hydrate: Drink plenty of fluids, especially water, to help thin the mucus and make it easier to expel.

- Steam: Inhaling steam can help to loosen phlegm and relieve congestion. You can do this by taking a hot shower or bath, or by using a humidifier.

- Cough: Coughing can help to expel phlegm from the lungs. However, be sure to cough gently and avoid coughing too hard, as this can irritate the throat and lungs.

- Avoid irritants: Certain irritants, such as smoke, pollen, and dust, can trigger increased phlegm production. Try to avoid these triggers as much as possible.

- Exercise: Regular exercise can help to improve lung function and reduce phlegm production. However, be sure to start slowly and gradually increase the intensity and duration of your workouts over time.

If you are still experiencing excessive phlegm production and difficulty breathing, it is important to see a doctor to rule out any underlying medical conditions.
