1. Drink herbal tea or green tea. Certain types of herbal tea are believed to help lower the amount of creatinine in your blood. Studies supporting this benefit are limited, but the theory has not been disproved, either. Drink around two 8-oz (250-ml) glasses of herbal tea each day. Herbal teas worth checking out include chamomile, nettle leaf, dandelion root. The idea is that these teas stimulate the kidneys and cause an increase in the production of urine. As such, more creatinine can be passed out of the body.
2. Consider taking nettle leaf supplements. Nettle leaf may help to increase your renal excretion, which will help to eliminate excess amounts of creatinine. Nettles contain histamines and flavonoids, which can help to increase the blood flow to your kidneys, thus increasing urine filtration. Nettle leaves can be taken in the form of supplements or can be made into tea.
3. Talk to your doctor about salvia. Salvia is an herb that may increase your glomerular filtration rate, which helps to facilitate the elimination of creatinine. Salvia contains lithospermate B, which helps to promote renal function. Set up a meeting with your doctor to discuss the possible use of salvia. Do not take salvia without consulting your doctor.
4. Watch your fluid intake. As a general rule, you should drink six to eight 8-oz (250-ml) glasses of water each day. Dehydration can actually cause your creatinine levels to increase, so staying hydrated is important. When you do not have enough fluid in your body, you produce less urine. Creatinine is washed out of your system through urine, so producing less urine will make it more difficult to flush out this toxin. On the other hand, consuming too much fluid could also have a negative effect on your kidney functions. Too much fluid could cause an increase in blood pressure, and high blood pressure can put stress on your kidneys. Unless otherwise instructed by a doctor, it is best to keep yourself hydrated but to avoid abnormal amounts of fluid intake.
5. Restrict your activity level. The body converts food into energy faster when it undergoes vigorous exercise. As a result, more creatinine is formed, causing the amount of creatinine build-up in your blood to increase. Exercise can still offer important health benefits overall, so you may not want to exclude it from your routine completely. You should swap out high intensity exercises for low intensity ones, however. Instead of running, weight lifting, or playing basketball, try walking or practicing yoga.
6. Sleep well. When you sleep, most of your bodily functions decrease. This includes the body's metabolism. As a result, the conversion of creatine to creatinine goes at a slower rate, allowing more of the creatinine already in your blood to filter out before additional toxins can build up. Aim for six to nine hours of sleep per night, with seven or eight being an ideal amount. Additionally, sleep deprivation can put physical stress on your entire body and force all of its parts to work harder to perform normal tasks. As a result, your kidneys can become stressed, which will decrease their ability to filter out creatinine.
7. Ask your doctor about stopping certain medications. There are some medications that have been associated with high creatinine levels. Medications that can damage the kidneys pose a possible threat, but some medications used to treat kidney disease can also cause a problem. If you already have kidney problems, be cautious about medications, like ibuprofen, that can cause further kidney damage when used regularly. ACE inhibitors and cyclosporine are both used to treat kidney disease but may cause creatinine levels to rise.
Some nutritional supplements, like vanadium, can also cause an increase in creatinine levels and should be avoided. Always talk to your doctor before stopping any medication. While some of these medications may cause creatinine to rise, the good could still outweigh the bad depending on why those medications were prescribed to begin with.
