When to Worry about Creatinine Levels Low or High?

Creatinine is a type of serum produced by the metabolism of muscles in the body. As creatine offers energy to the muscle, its by-product, creatinine, is absorbed in the blood. While the body continuously produces creatinine, kidneys extract this substance from the blood and excrete it out of the body. 

Creatinine is a key metric used to evaluate kidney function and general health. Understanding its importance can aid in the diagnosis and treatment of a variety of health disorders because it plays a key role in the body. Here are some crucial details emphasising the importance of creatinine:

1. Kidney function
2. Diagnostic tool for kidney diseases
3. Evaluation of medication dosage
4. Muscle mass indicator

The normal range of serum creatinine in the blood is 0.6 to 1.2 mg/dL (for males) and 0.5 to 1.1 mg/dL (for females) when the kidneys function properly. Any deviation from the accepted range indicates a serious underlying health condition. 

Furthermore, doctors use a creatinine clearance test to determine how efficiently your kidneys can remove creatinine from the bloodstream. The person may require medical guidance if the levels are higher or lower than normal.

It is difficult to recognise impaired kidneys because a reduced kidney function shows no discernible symptoms. Most physical symptoms manifest only later when the kidneys are already damaged.

If creatinine levels fall below the normal range, it may suggest a health-related anomaly in the body. Some symptoms commonly identified with low creatinine levels are

1. Fatigue or Weakness
2. Muscle Cramps
3. Breathing difficulties
4. Changes in urination
5. Nausea
6. Brain fog
7. Lack of appetite

Nevertheless, any drastic change in serum creatinine levels is not only caused by kidney damage. Other temporary and chronic underlying conditions can alter the serum creatinine levels in the blood. Find below some of the causes that may lead to low creatinine levels: 

1. Low Muscle Mass: Creatinine levels in the body are mostly linked with muscle mass or the amount of muscle in the body. With increasing age, the muscle mass decreases, which eventually leads to low creatinine levels.
2. Liver Disease: The liver produces creatine, which is then absorbed by muscles and forms creatinine. When the liver does not function properly, it fails to produce sufficient amounts of creatine. 
3. Malnutrition: Creatinine is a by-product of creatine phosphate in muscle, and its production is proportional to muscle mass. If there is not enough creatinine in the blood, it may result from a severe lack of muscles in the body. It may also indicate a lack of protein in the diet. 
4. Pregnancy: Pregnancy is often a contributing factor that reduces creatinine levels in the blood. It is a temporary condition, and the serum creatinine levels restore to normal after giving birth. 

Risks Factors of Low Creatinine Levels 

While low creatinine can be a temporary condition resulting from numerous external reasons, it may also indicate some severe health anomalies. On the contrary, a higher amount of creatinine in the blood almost invariably indicates impaired kidney function.

The following are some of the risk factors that might contribute to low creatinine levels in the body:

1. Older age
2. Obesity
3. Diabetes mellitus
4. Kidney dysfunction
5. Family history of kidney disease
6. Medications that affect kidney functions
7. High blood pressure
8. Cardiovascular disease 

A thorough assessment by a healthcare professional is required to diagnose low creatinine levels in order to discover the underlying cause and the best course of treatment. Here are some typical diagnostic procedures and examinations that may be carried out:

1. Medical Assessment: The healthcare provider will begin by getting a complete medical history, which will include any known illnesses, drugs, and symptoms. They could enquire about conditions, including muscle atrophy, liver illness, or kidney malfunction that could cause low creatinine values.
2. Blood and Urine Tests:  A vital tool for identifying low creatinine levels is a blood and urine test. Creatinine levels in the blood can be determined using a comprehensive metabolic panel or renal function panel. Low levels of creatinine can be used to evaluate renal function and pinpoint likely reasons, along with other pertinent blood indicators.

Treatment for low creatinine levels focuses on addressing the underlying cause and restoring normal creatinine levels. The specific treatment approach will depend on the underlying condition contributing to low creatinine. Here are some common treatment strategies:

1. Treating Underlying Medical Conditions: The main focus will be on managing and treating the underlying medical condition if low creatinine levels are brought on by liver disease or kidney dysfunction. This could entail using drugs, altering one's lifestyle, or undergoing other prescribed measures.
2. Medication Adjustment: Medication side effects might occasionally cause low creatinine levels. To return creatinine levels to normal, medical practitioners may examine and modify the amount or kind of medicine. Before changing a patient's prescription regimen, it's crucial to speak with a healthcare professional.
3. Improving Muscle Mass: If muscle wasting or loss is the cause of low creatinine levels, improving muscle mass may be advised. This can involve regular exercise, resistance training, and physical treatment to encourage muscle strength and growth. A medical practitioner or trained fitness specialist can offer advice on proper workouts and intensity levels.

It's crucial to regularly check your creatinine levels so you can judge how well your treatment is working and make any required adjustments. For the purpose of monitoring creatinine levels and assessing renal function, this may entail routine blood tests.

Follow-up consultations with a medical expert will enable the continuing assessment and management of reduced creatinine levels.

Low creatinine levels in an individual can lead to kidney disorders and eventually lead to poor quality of life. Thus, it is important to understand and undertake preventive measures to improve creatinine levels. 

Lifestyle Changes 

Following a healthy diet plan, the next action must be following a healthy and moderately active lifestyle to boost muscle mass. 

A lack of creatinine indicates a severe lack of muscle mass. It impacts a person’s physical appearance, hampers their stamina, and comes in the way of a healthy life. Incorporating some of the following physical activities in your everyday life can improve creatinine levels while also improving the quality of life:

1. Walking: Moderate to fast-paced walking is a great way to work your leg muscles. Weekly training increases the stamina of a person while also improving skeletal quality and overall body strength.
2. Swimming: It is one of those activities that can target all the muscles in the body, making it a great option for full-body exercise.
3. Weightlifting: Start with a small amount of weight and fewer repetitions and increase over time as your tolerance increases. Perform this only after two weeks of changing your diet and lifestyle. This is one of the most effective ways to increase body mass, thereby increasing creatinine quantity in the blood.  
4. Bicycling: Few physical activities are effective as well as refreshing at the same time. Light to moderate bicycling regularly is a useful cardiovascular activity to build your stamina while also targeting the core, quads and hamstring muscles.

Hence, including a few of these changes in your life is a great way to increase serum creatinine levels in the bloodstream naturally. 

Dietary Changes 

When it comes to low creatinine levels, an inefficient diet plan almost invariably lies at the root of the cause. Nowadays, poor-quality diets and heavy dependency on fast foods are one of the factors that cause lower creatinine levels in the blood. 

Incorporating more nutritious whole foods in your diet effectively increases the creatinine quotient in your blood. Food items rich in macronutrients promote muscle development and increase serum creatinine in the blood. You may include some of the following foods in your diet:  

1. Meat: Red meats are a rich source of protein in the human body. It helps efficiently build lean muscle mass while contributing to increased creatinine production.
2. Eggs: Eggs are a great source of protein and good fats. Make it a part of your everyday diet to build stamina and fill your body with healthy nutrients.   
3. Lentils: If you are a vegetarian, several foods rich in protein can produce positive results for your body. Various groups of lentils are a rich source of protein and micronutrients to balance your creatinine levels. 
4. Legumes: Legumes and several classes of beans such as soybean, chickpeas and kidney beans are a great source of antioxidants. They flush out toxins from the body and promote better digestive health. These proteins are also easily digestible and the body absorbs them more efficiently.  
5. Greek Yoghurt: Greek yoghurt is a rich source of protein, Vitamin B12 and selenium along with several gut-friendly bacteria that helps neutralise stomach acids. It also boosts metabolism, which promotes better digestion and protein absorption in the body.
6. Creatine Supplement: You may also opt for over-the-counter creatine supplements to boost your creatinine levels. These supplements help to develop muscle mass in the body, so ensure you are engaging in moderate strength training for best results. 

Blood absorbs a very small amount of creatinine from food; most of the creatinine in the bloodstream is produced in the body.  So, building healthy muscle mass is essential to improve creatinine levels in the blood.

If your lab tests for serum creatinine indicate higher than normal range or, below the normal range, you should visit a nephrologist. A nephrologist is a specialist in kidney function who can accurately identify related health problems. They may prescribe further tests to provide an accurate diagnosis regarding your condition.

Here are some situations where you should seek medical attention:

1. Persistent or Unexplained Low Creatinine Levels: If your creatinine levels remain low over several tests or your doctor can't explain why your creatinine levels are low, it's essential to see a doctor.
2. Symptoms of Kidney Disease: Symptoms of kidney disease can include fatigue, nausea, vomiting, swollen ankles, and changes in urination.
3. History of Kidney Disease: If you have had a history of kidney disease or kidney issues, you should consult a doctor to ensure your low creatinine levels aren't an indication of a condition worsening.
4. Taking a Drug that Interferes with Kidney Function: Some drugs, including diuretics, can decrease creatinine levels. You should speak to your doctor if you take medication that affects kidney function and has low creatinine levels.
5. History of Kidney Disease in your Family: If kidney disease runs in your family, you should visit a doctor to ensure that your low creatinine levels aren't a symptom of an inherited disease.

It is important to get a diagnosis as soon as possible to discern the cause behind the abnormal creatinine levels and get it treated properly.

Low levels of creatinine can be concerning since they could be a sign of a health problem or physical imbalance. Although occasional changes in creatinine levels may not be concerning, persistently low values should be assessed by a healthcare provider. Individuals can better determine when to seek medical assistance by being aware of the possible risks, causes, and symptoms connected with low creatinine levels.
