Talk to Cardiologist on Shortness Of Breath And Fast Heart Beat Due To Hypnoxia

AoA all.

Since last week or 2, I have been feeling very low, lazy, lethargic, fatigued, tired. Till few hours earlier I did not know why this is happening and what might be the cause of it. Now I have read something on the net and found that the symptoms I have been feeling is called Hypoxia.

Can any Doctor guide me how to control this and what causes it and what I need to do and follow to get rid of it or this continues or will be over after some time after taking precautions or medications.

Symptoms :

Sleepy and goes to sleep quickly while sitting, in day time during working hours.

Feel shortness of breath and heart starts pounding and feel breathing in belly while sleeping at night.

Checked pulse oximeter and found oxygen level is under tolerance 97-99 every time I checked.

Please advise, is this normal or should I visit my GP or concern doctor only.

*** I drink very less water like 3-5 glass a day.

Thanks
