10 Warning Signs of A Heart Attack
Warning Sign #2: Lightheadedness
It is essential that we supply our brain with all the nutrition and oxygen that it needs. If it does not get enough oxygen then it will struggle to function as it should, and permanent damage is a possibility. One of the first symptoms of sufficient oxygen reaching the brain is feeling lightheaded, and this can be a sign of a heart attack.
In the case of a heart attack, the blood pressure will drop due to the inability of the heart to effectively circulate the blood in sufficient volumes. This will decrease oxygen levels in the brain and we will become lightheaded as a result.
