How to reduce ferritin levels?
Even among healthy young people, SF and iron stores can be reduced by blood donation or therapeutic phlebotomy. Phlebotomy has been demonstrated to reduce SF, and multiple other disease markers, including GGT, in patients with chronic hepatitis C [66]. In the case of pregnant women, excessive iron stores during pregnancy can be moderated by reducing or ceasing iron supplementation when iron stores are adequate, or by making appropriate dietary adjustments, including lowering dietary iron intake. When conditions of disease risk, such as prediabetes, insulin resistance, or prehypertension, exist before pregnancy, supplementation of alternative nutrients such as curcumin extract might be considered. Curcumin has been noted to enhance several protective functions, including improving glutathione status, by lowering serum GGT levels [67] and by chelating potentially toxic iron as described by Minear et al. [68]. In a recently reported randomized, double-blinded, placebo controlled trial, undertaken in Thailand, subjects randomized to the treatment arm received curcumin (the main curcuminoid found in turmeric) in extract form. Chuengsamarn et al. [69] reported that, among biomarker improvements achieved by subjects in the treatment versus placebo arms, perhaps the most notable was reductions in levels or insulin resistance (as measured by HOMA-IR). Subjects who received curcumin extract achieved the following (mean) reductions in HOMA-IR levels versus the levels of subjects in the placebo control group: three months 0.37 (not significant), six months 0.64 (P< 0.05), and nine months 0.86 (P< 0.001). The curcumin arm subjects also achieved improvements in body weight (lowering) and waist measurement, bothP< 0.05 over nine months, fasting plasma glucoseP< 0.01 at three, six, and nine months, two-hour OGTTP< 0.01 at each time interval, and lower HbA1c alsoP< 0.01, also at each time interval. Several other significant improvements were also noted. Importantly, the investigators found the treatment to be safe, and no subjects in the curcumin treatment arm converted to a diagnosis of diabetes, while 16.7 percent of the subjects in the placebo arm were diagnosed with diabetes by the end of the one-year study.
What was the first study to measure GGT?
The first American epidemiologic study to test GGT levels was the Framingham Offspring Study (FOS). Between 1978 and 1982, 3,853 participants in the second phase of FOS were evaluated for most of the standard heart disease risk factors, including body mass index (BMI), alcohol consumption, smoking, blood pressure, lipids, liver enzymes (including GGT), fasting blood glucose, serum creatinine, C-reactive protein (CRP), and the presence of diabetes. Participants were followed up for a total of 20 years, with an interim assessment after 8 years to ascertain incidence of MetS. In 2007, Lee et al. [9] reported that baseline measures of GGT were significantly related to the onset of MetS by the end of the 8-year interim period. The relationship of GGT to MetS followed a dose-response relationship across each of participant quartiles 2 through 4, when compared to the first GGT quartile. Baseline peak GGT measures in the first quartile were 6 U/L for women and 11 U/L for men. After adjusting for age, gender, and alcohol use, and compared to participants in the first GGT quartile, the hazard ratios (HRs) for new onset MetS for men and women combined were 1.46 in quartile two, 1.83 in quartile three, and 2.54 in quartile four. The HRs were significant to P≤ 0.001 for quartiles three and four, and P< 0.05 for quartile two. At the end of the full follow-up period (mean of 19 years), a total of 968 participants developed MetS and 535 incident cardiovascular disease (CVD), and 362 died. After multiple adjustments for standard CVD risk factors, participants in the highest GGT quartile experienced a 67% increase in CVD incidence (fully adjusted HR 1.67 (95% CI; 1.25 to 2.22)).

What is GGT in health?
4. GGT: A Predictor of Obesity, MetS, Prehypertension, and Insulin Resistance
Is insulin resistance a factor in gestational diabetes?
In the study described directly above, GGT levels relative to the future development of insulin resistance is of special interest because insulin resistance has recently been noted to be a key factor, when combined with serum GGT levels, for forecasting future development of gestational diabetes (GD M). In 2014, Sridhar et al. [60] reported findings from their case-control study of a large cohort of young women (n= 4,098) in Northern California who were tested between 1984 and 1996 for levels of both insulin resistance and GGT. Testing was on average completed seven years prior to either the woman's first or next subsequent pregnancy. A total of 267 women experienced GDM during their subsequent pregnancy. Among the women with BMI levels above 25, those with GGT levels above the cohort median of 18 U/L experienced GDM at two times the rate of women in the first GGT quartile (GGT 8.0–13.4 U/L). While women with BMI over 25 at study entry in the second GGT quartile (GGT 13.5–18.0 U/L) did not experience increased GDM risk, women in the second GGT quartile having BMIbelow25 at study entry experienced a 1.8-fold increased risk of GDM. The risk of lean women was similar to that of the heavier women, when GGT levels were above the median of 18 U/L. Notably, Sridhar et al. reported that, when the interaction of insulin resistance (assessed by HOMA-IR) was added to the risk analyses, the HRs changed markedly. Women who had GGT above the first quartile (13.5 U/L), together with insulin resistance measured in the upper tertile of HOMA-IR, experienced increased GDM HRs, compared to first quartile GGT and HOMA-IR (in the lower two tertiles), of 2.7, 3.8, and 4.9 in the second, third, and fourth quartile of GGT, respectively. Interestingly, GGT alone, as reported in any quartile in this study, did not pose a risk of GDM when insulin resistance (assessed by HOMA-IR) was measured in the lowest two HOMA-IR tertiles. The significant interaction noted here was very similar to that noted above by Targher et al. [54] when serum ferritin and GGT measures were analyzed to both assess the risk of incident IFG and diabetes in their study cohort and calculate the interaction of each of these risk markers. Thus, GGT interacts with both serum ferritin and insulin resistance to enhance disease risk.
Why is GGT elevated?
Follow Us: Elevated levels of the liver enzyme gamma-glutamyl transpeptidase, or GGT, may be caused by habits and conditions that damage the liver, including overconsumption of alcohol and drugs, hepatitis, loss of blood flow to the liver and cirrhosis of the liver, according to Healthline .
