Hello, The ideal saliva pH pattern is 7.2 on awakening, 6.8 to 7.2 before eating and 7.2 to 8.5 following any alkaline meal or drink. Your saliva should be slightly alkaline to begin the pre-digestive process.
Your symptoms sound like "acid reflux" to me. You may have a condition called "GERD" Gastroesophageal reflux disease, or GERD, is a digestive disorder that affects the lower esophageal sphincter (LES), the ring of muscle between the esophagus and stomach. Many people, including pregnant women, suffer from heartburn or acid indigestion caused by GERD. Do you have any tummy pain with this or just the acid in the throat?
I would suggest taking 2 tablespoons of Aloe Vera juice at night before bed, this has helped me immensely. Aloe vera is a healing plant and really helps stomach and digestive issues. It is not expensive, it can be purchased at any health food store and some pharmacies.
Are you eating on a regular basis? Excess stomach acid can happen from not eating or having an empty stomach for extended periods of time.
There are over the counter antacids that you can take that can ease the acidic stomach, or eating a small meal or snack can help reduce the build up of stomach acid.
If it continues, a consult with your primary can help rule in or out any cause for concern.
Prolonged, month and years of excess stomach acid can cause problems, but short term increases in stomach acid generally aren't dangerous, unless there are other medical conditions related to the increased acid.
Sounds like heartburn , you can get stuff in shops/ pharmacy for it over the counter
