What is direct bilirubin (conjugated bilirubin) and normal values

Direct bilirubin (also known as conjugated bilirubin) is a type of bilirubin that is included in routine blood tests. Find out what it is and what you can do to lower it when it’s high.

As many of you know, bilirubin is a yellowish bile substance that is produced after degrading hemoglobin from red blood cells inside the spleen to finally take it to the liver, the organ where bile is produced.

Among the main functions of bilirubin, it should be noted that it acts as a kind of cellular antioxidant and is also responsible for promoting better digestion of all the fats in our body.

Within bilirubin we find two types. First, there is direct or conjugated bilirubin, which is what we will mention in this Natural article. This consists of a mixture of glucuronic acid that then accumulates to create bile.

We must also name what is known as indirect bilirubin, which basically consists of bilirubin in albumin before mixing with glucuronic acid. For this reason, it is a type of fat-soluble bilirubin, which cannot be eliminated through the urine, as is the case with direct or conjugated bilirubin.

Normal values ​​of direct or conjugated bilirubin

In a blood test, one of the elements that are usually analyzed is bilirubin, which is also divided into the different elements that we have indicated above.

Regarding direct bilirubin itself, the normal value of this substance in an adult should be  between 0-0.3mg/ld. On the other hand, we have unconjugated bilirubin, which we will talk about later.

What are the symptoms of high direct bilirubin?

At normal levels, this yellow pigment is most relevant when it comes to balancing and strengthening our body. However, if the levels skyrocket and we have high bilirubin, this situation can have serious consequences for our health. And therefore, we will have to be very attentive to certain symptoms that we will break down below:

  • Stitches in the abdomen. It is very normal to feel all kinds of discomfort in the areas near the liver and that show us that bilirubin levels are too high.
  • One more sign that this yellow pigment has exploded in our body is that when we go to the bathroom, all our stools have a very intense yellow color.
  • Fatigue and feeling unwell. It is also very likely that you will experience tremendous discomfort after a meal if your bilirubin levels are not correct. All this can be accompanied by strong vomiting. 

What to do if you have high direct bilirubin?

Before the appearance of any of these symptoms, it is very important to visit our trusted doctor as soon as possible in order to make a puncture and take a blood sample.  Thanks to it, you will be able to know what the total bilirubin levels are (which is the mixture of direct and indirect).

It seems very important to follow the doctor’s instructions at all times before taking the sample. You must always go fasting so that the samples are always as accurate as possible and without having eaten anything during the past 12 hours.

We also have to let you know if we have taken any substance that could have increased the levels of this pigment in our blood (such as alcohol or a meal rich in fat) together with a medication that could vary the final results.

In summary, if what we want is that the levels of direct bilirubin do not skyrocket, we just have to eat a healthy and balanced diet in all kinds of nutrients along with some habits that make us say goodbye to a life of more sedentary.
