Is it safe to drink beetroot juice on an empty stomach?

Beetroot is a nutritious vegetable that can purify the liver while adding a healthy glow to the skin. Smoothie lovers often mix vegetables with their breakfast juices, fruit bowls, and various other meals. Many health enthusiasts also habitually start their day with vegetable juice. However, drinking beetroot juice daily on an empty stomach can have some risk factors. It can sometimes lead to indigestion, gas and bloating due to its high oxalate content and a detox effect, resulting in acid reflux. Here are a few of the other risk factors it can cause: 
Drops blood sugar level
Those who suffer from a quick drop in blood sugar level should not drink beetroot juice on an empty stomach as it hinders the glucose level, dropping the blood sugar.

Kidney stone
Small stones may form in the kidneys as beetroot contains oxalates.
Discolouration of urine
Although this is not a severe disease, it could lead to serious health problems if ignored. Drinking beetroot juice on an empty stomach may cause urine and stool discolouration, which is a condition called beeturia.
Low blood pressure
Those with low BP should not drink beetroot juice on an empty stomach as the blood pressure may drop rapidly.

Allergy
Pigmentation on the skin, swelling on the face and lips and difficulty breathing are some of the symptoms of allergic reactions caused by drinking beetroot juice.
Not good for liver
Beetroot is a storehouse of iron, copper and other heavy metals. So, those who suffer from liver-related illnesses should not consume beetroot.
When is the right time to drink beetroot juice?
Experts say that this nutritious homemade juice could be enjoyed after breakfast. Those suffering from certain medical conditions can drink beetroot on an empty stomach, per the doctor’s advice. Meanwhile, a healthy person should drink this juice only after having breakfast.
