Drooling during sleep should not be ignored, as it can be a symptom of an underlying illness. Xiao Liang, 25, from China, is a programmer. Due to his heavy workload, he often has to work overtime, and even after exhausting workdays, he stays up late playing video games.
This also makes him very sleepy every morning and he doesn’t wait until lunchtime to start sleeping.
Xiao Liang discovered that he drooled in his sleep, which embarrassed him greatly. To solve this problem, he decided to consult a doctor.
After the doctor learned that Xiao Liang frequently drooled in the same direction, he asked that he first have a CT scan of his brain.
Unexpectedly, the examination revealed that Xiao Liang’s cerebral blood vessels showed signs of obstruction. Fortunately, it was detected in time, thus preventing the risk of stroke and brain hemorrhage.
