Caustic ingestion occurs when someone accidentally or deliberately ingests a caustic or corrosive substance.Depending on the nature of the substance, the duration of exposure and other factors it can lead to varying degrees of damage to the oral mucosa, the esophagus, and the lining of the stomach.
Oxalic acid binds with calcium to form calcium oxalate crystals which may deposit and cause damage to many areas of the body including the brain, heart, kidneys, and lungs. [7] The most significant effect is accumulation of calcium oxalate crystals in the kidneys which causes kidney damage leading to oliguric or anuric acute kidney failure. [7]
Essential fatty acids, such as omega 3s, are key to the strength and performance of the brain’s cells. Since the human body can’t produce essential fatty acids on its own, they must come from ...
Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion. Substances that diffuse efficiently in human tissue, e.g., hydrofluoric acid , sulfur mustard , and dimethyl sulfate , may not react immediately, but instead produce the burns and inflammation hours after the contact.
Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs. [59] These effects are believed to be due to hydrogen sulfide combining with alkali present in moist surface tissues to form sodium sulfide , a caustic . [ 66 ]
The internal wall of the canal is very delicate and allows the fluid to filter due to the high pressure of the fluid within the eye. [7] The secondary route is the uveoscleral drainage , and is independent of the intraocular pressure, the aqueous flows through here, but to a lesser extent than through the trabecular meshwork (approx. 10% of the ...

As little as 10 mL of pure methanol when drunk is metabolized into formic acid, which can cause permanent blindness by destruction of the optic nerve. 15 mL is potentially fatal, [1] although the median lethal dose is typically 100 mL (3.4 fl oz) (i.e. 1–2 mL/kg body weight of pure methanol). [4] Reference dose for methanol is 0.5 mg/kg/day. [9]
