Growing number of women claim unpleasant symptoms such as nausea, lightheadedness, fainting, and dizziness occurring right after sexual intercourse. There are many possible reasons for experiencing these symptoms, some of which are particularly related to the intercourse while others aren't.
Innervation of Genital Organs
Innervation of vagina and clitoris stems mainly from autonomic nervous system which consists of parasympathetic and sympathetic part. During intercourse, these nerve endings can be overstimulated thus resulting in transient disturbances in the function of autonomic system. As this complex system also controls bowel movements, blood vessels and other smooth muscles in our body, it is clear why the above symptoms may appear during and after vaginal stimulation. Also, different sex positions and a lot of motion and shaking can cause reflex stimulation of vagus nerve, thus resulting in nausea, dizziness, and other unpleasant symptoms that are similar to motion sickness.
Autonomic System Dysfunction
Some persons might have disturbed function of autonomic nervous system even if they don't know it yet. These manifestations occurring after intercourse can be the only clue and a hint that you should visit your doctor to do necessary examinations. Autonomic system dysfunction can also cause postural hypotension (dizziness, fainting, and vision problems when standing up), frequent urination, sexual dysfunction, nausea, diarrhea, etc. If you experience any of these symptoms, you should contact your health care provider for further examination.
Sex After Eating
Having sexual intercourse, just like any after greater physical activity after heavy meal, can disturb digestion and cause nausea, vomiting and other gastrointestinal symptoms. The mechanism is very similar to the above stated, as the vagus nerve is overstimulated in this case too. Make sure that you give your digestive system enough time to process the food before sex.
We live in a world filled with stress, and sometimes it is difficult to relax enough to have a normal sex life. So stress can produce these problems, too. If you rule out organic problems, a psychologist may help you resolve if there are any psychological issues affecting your sex life.
As women report different symptoms regarding this issue, we can conclude that the causes are also variable. Before contacting your doctor, try improving your lifestyle by doing some exercises and losing excess weight as that can help you resolving the problem. Try finding the way to relax and eliminate stress. Sexual intercourse should be pleasurable for both men and women and you should find out what produces your unpleasant symptoms.
