Is it safe to drink sodium bicarbonate solution to test the level of acidity in my stomach at home (without referring to my doctor)?

Need pH testing: Ph testing can check your esophagus for exposure to substances regurgitated from the stomach-- for acid (such as bravo ph capsule implanted on your esophagus) as well as non-acid reflux (ph impedance testing). The test correlates your symptoms in real-time with what refluxes. Ph testing also has utility in assessing the efficacy of acid-blocker drugs. Drinking bicarbonate (sodium bicarbonate) puts kidneys at risk.
