As we mentioned before, creatinine is the metabolism product of muscles and
when kidney function is damaged, serum creatinine will rise. Some asked whether
creatinine will fall when kidney disease takes places. The answer is no. When
will creatinine level becomes low and what is the cause of low creatinine
level?
1.age
Generally, advanced people may have a lower creatinine level, as the muscle
mass tends to decrease with age. Aging causes a natural decline in the amount of
muscle mass in the body. In addition, young children also have a normal
creatinine level that is lower than that of adults. Creatinine levels are
usually higher in men because their muscle mass is higher than that of women. In
people who have decreased muscle mass, creatinine levels may be low.
2. diet
If the food we take in is low in protein, we can suffer low creatinine. It is
generally believed that food which is high in creatine phosphate such as salmon,
pork, tuna and beef is rich in protein. Because these foods are not included in
a low-protein diet, there is less creatine phosphate to break down, which leads
to reduced creatinine levels.
3. pregnancy
Pregnancy can also lead to low serum creatinine. once the fetus comes into
being, they will grow, which leads the nutrients into baby from mother. In this
case, pregnant mother will have less creatine phosphate to break down, which
will also leading to reduced serum creatinine. However, after the childbirth
occurs, creatinine level in serum will turn normal in most of the cases.
4.debilitation and low creatinine levels
Muscles atrophy when they are not used, and as the muscle mass decreases,
creatinine levels will fall. This can happen with a debilitated patient,
especially someone who has lost muscle tone from being bedridden or
hospitalized.
