Ingesting too much acidic fluid without proper precautions can rot your teeth, make you feel sick, and possibly even affect kidney function.

Swallowing too much apple cider vinegar can rot your teeth, make you feel nauseous and even affect kidney function
It can erode the enamel
Drinking too much apple cider vinegar can rot your teeth.
That’s because the vinegar, as anyone who’s tried a shot can attest, is highly acidic.
Drinking it undiluted can erode the enamel, the hard protective layer on your teeth, the NHS warns.
It is recommended that people do not drink the vinegar straight, but instead mix one to two tablespoons into water or another drink, or add it to a food dressing.
This dilution does not affect the supposed health benefits, but it does reduce the risk of apple cider vinegar eroding your pearly whites.
If the enamel on the surface of the tooth becomes damaged, plaque and bacteria can reach the softer bone-like material underneath, causing further erosion and even cavities, the NHS warns.
A case study of a 15-year-old girl revealed that her tooth decay was caused by drinking 8 ounces of undiluted apple cider vinegar per day in an attempt to help her lose weight.
It can damage your throat and skin

Some believe that suing the vinegar helps to balance the PH levels in the skin and some people also use it as a treatment for pimples.
But researchers from the University of Auckland reported Direct application to the skin has also been shown to cause skin irritation and chemical burns.

Possible side effects of taking apple cider vinegar directly include acid reflux, nausea and slowed digestion due to its high acidity according to a 2018 study. study by researchers from Middlesex University.
While one controlled study suggested that the vinegar could reduce food intake and therefore logically help with weight loss, it also found that drinking it made digestion worse.
The 2014 study reported that although people who consumed 25 grams of apple cider vinegar reported less appetite, this was mainly because they felt more nauseous.

Should be avoided if you have kidney problems
If you have chronic kidney disease, your body may have difficulty processing the excess acid from the apple cider vinegar.
This can cause a buildup of acid in your body, called metabolic acidosis.
As this acid increases, your kidney function decreases, and as kidney function decreases, so does its ability to process the acid, the National Kidney Foundation warns.
A fast heart rate, feeling very tired, loss of appetite, vomiting and the need to take deep, long breaths are all symptoms of metabolic acidosis.
Allergic reactions
Anyone with an allergy to apples or pectin, a fiber found in fruit, should also avoid apple cider vinegar.
An allergic reaction can cause swollen lips, swollen eyelids, stomach cramps, rash and an itchy feeling in the throat, the NHS says.
