Hi doctor! I am 19 years old this year, the normal heart beat ranges from 100-110 times / minute. Recently, even though I haven't exercised vigorously, my heart rate sometimes rises to 120-125 times / minute, dizziness and shortness of breath.

Hi doctor! I have dizziness for about 1 hour, what's wrong, doctor? Is this situation dangerous, please advise me. I thank you!

Vertigo is a feeling of loss of balance, making you feel like you or your surroundings are spinning, tossing, or turning, causing you to lose your balance and fall. The pathogenesis of vertigo is complex and treatment depends on the cause of the vertigo.

There are many causes of dizziness and nausea, such as reduced cardiac output, the aftereffects of a migraine, or excessive anxiety. Dizziness and vomiting will usually go away without treatment, but you should seek medical attention if you vomit or pass blood, pass out, or your symptoms do not improve within 2-3 days.
