What are key functional insights related to Glucose?
πΉ Marker Description: Primary marker to get understanding of blood glucsoe / insulin reisstance / metabolism
Low glucose = glucagon released = blood glucose increase = insulin increase
Glucose utilisation in liver
Level of glucose in the blood is highly dependant on the liver through the breakdown of glycogen and via the adrenal glands which produce hormones that promote the gluconeogenesis (generation of glucose) from fats and proteins.
required by most cells for energy productin - brain and NS rely solely on glucose for energy
fasting glcose evaluate blood sugar regulation - insights into diabetes and insulin resistance
regulating blood sugar also reliased on hormonal function
Adrenaline, cortisol, thyroxine
π» Possible Low Reasons: reactive hypoglycemia (low blood sugar diet , fasting, strenous exericse) - often happens when excessive glcusoe consumed, then ‘delayed reollarcoaster’ = brings down blood glucos - but too low
OR possibly hyperinsulinism - chronic high blood sugar diet - chronic pancreatic overstimulation (reactive hypoglycemia) low level blood glucose - high insulin (Glut4 allows serum glucose to enter cell - low in blood)
Insulin resistance - might also see brown / red tint on shins
adrenal hypofunction
hypothyroidism - body might not be stim. as much gluconeogensis . check if low TS3/TS4 as well - could help improve thyroid.
Liver issues (cannot control blood sugar, glycogen storage issue)
- if see low glucose + high GGT, AST, high ALT - assess if it hypoglycemia is related to liver dysfunction [hypoglycemia = gluycogen storage issue ]
chronic stress: decerased cortisol - can see with chronic stress, lack of sleep, HPA axis dysregulation.
- adrenal hypofunction if chornic stress (addisons disease)
- tissue insentivity
medications (metformin, proranolol, tolbutamide)
low vit d.
tumours of pancetaic cells (beta cells - insulinomas)
- glycogen release issue (adrenal-foucsed treatment)
addisons disease
πΊ Possible High Reasons: Insulin resistance
Metabolic syndrome, Fatty liver, fasted NAFLD/MAFLD, diabetes
Acute/chronic stress!! - adrenal hyperfunction/cortisol resistance (stress hormones - cortisol,NE increases glucose - dyesregulated HPA axis (eg lack of sleep, anxiety etc))
Low insulin - Adrenal hypofunction- low secretion of cortisol from adrenal glands
Binging
Pancreatic issues!!! Severe renal disease.
PCOS
Medications - corticosteroids, thizaides, phenytoin, oestrogen
vit b1. deficiency
adrenal hyperfunction, hyperthryoidism, cushings disease
ALSO - could be due to stress - eg were they rushing that morning? was someone annoying them on the road? did they have an argument? etc
Cowβs milk proteins and some vaccines may trigger an immune response against pancreatic beta cells, increasing the risk of type 1 diabetes in genetically susceptible individuals.

What are key functional insights related to Insulin?
πΉ Marker Description: Insulin is a hormone secreted by the pancreatic beta cells in response to rising blood glucose levels.
It regulates glucose uptake and storage, playing a key role in metabolism and energy balance.
A fasting insulin test (after 12 hours of fasting) helps assess insulin sensitivity, resistance, or pancreatic function.
- v fast acting /to change (done after 12 hour fast - any more than 12 hours = insulin levels drop too mcuch
- Need to pay attention to insulin - but because it is such a small half life - pay more attention to HPM1C - can assume elevated insulin (and decreased AMPK)
In healthy individuals, insulin:
Regulated blood glucose and storage:
- Transports glucose into cells, making them more permeable to glucose and lowering blood sugar levels.
Instructs the liver to convert excess glucose into glycogen (short-term energy storage).
Promotes fat synthesis (long-term energy storage) when glycogen stores are full.
Also maintains Protein Function & Gut Integrity
- Insulin regulates proteins like zonulin, which is essential for maintaining intestinal barrier integrity.
- this is impaired in insulin resistance / hyperinsulinemia
- high insulin = downregulates AMPK = paracellular leakage (integrity breaks)
produced by pancreatic b cells -
π» Possible Low Reasons: fasting
diabetes (T1 ) - pncreatic cell dysfunction
pancreatic cancer, pancreatitis (low insulin + high blood glucose indicate damage to beta cells => can cause insulin-dependancy eg in T2D), beta cell damage, pancreatic islet b cells AI
macronutrient deficiencies (eg eating disorder) - (eg if see low insulin, low glucose, low Hb, low ferrtiin,low total protein)
πΊ Possible High Reasons: insulin resistance (prolonged exposure to insulin - receptors not sensitive - body keeps producing more insulin to compensate to try and get it to bind - pancrease has to make more and more)
- also inflammation in insulin resistance can also affect insulin - ecsp. if fertility issues (eg PCOS, hair loss - may want to look into adnrogen)
hypglycemia
obesity, high trans fat intake
cushings disease,
PCOS (as SBG is lower)
medications - corticosteroids, oral contraceptive pills, levodopa (AD)
h.pylori
paracellular permeability (>7 mU/L)
π Patterns: Low insulin, High Blood Glucose = pancreatic cell damage
Pay attention to HPA1C as T1/2 insulin low
What are key functional insights related to HBA1C?
πΉ Marker Description: Stickniness’ of RBCs
- glycated hemoglobin = measures the % of hemoglobin in red blood cells that has glucose attached to it.
- Reflects av. blood glucose levels over the past 2-3 months (120 days), giving a long-term picture of blood sugar control.
- Glucose combines with Hb to produce glyco-Hb indicates blood sugar levels over 120 days
2-3 month lag (120 days) - so good marker of change in diet
- eg if glucose and insulin have improved, but HB1AC still high - sign that diet has improved over past 2 months
- think of it like hunny - cells become stickier - measures blood glucose levels over RBC life span
- Glucose binds to hemoglobin, forming glycohemoglobin in a non-reversible reactionβmeaning RBCs remain “sticky” for their lifespan (~120 days)
Used to assess diabetes risk, blood sugar regulation, and metabolic health trends.
Seasonal & Diurnal Variations:
- Higher in winter than summerβcold increases metabolic demand.
- Higher in the morning than afternoon due to overnight glucose dynamics.
- Suggests higher glucose efficiency is needed in colder environments.

Very high Vitamin D levels β Requires testing of active form (1,25-OH D), not just standard Vitamin D.
Other Risk Factors:
- Male, African American ethnicity,
sleep apnea,
renal failure, low water (dehydration), excessive exercise
high BMI, hypercholesterolemia, hypertriglyceridemia.
myerlorproliferative neoplassms)
π Patterns: Conv: 150-350 umol/L / 2.4-6 mg/dL
Molybdenum deficiency - L Uric Acid
Heavy metal toxicity: H BUN, uric, acid, bilirubin, globulin. L Platelets.
Renal disease: H creatinine, uric acid, phos., LDH , AST
Transcellular: H monocytes, H uric acid, L or H ALP, L ferritin, H CRP, H ESR
(secondary: H basophils, eosinophils, homocysteine, L total protein
tertiary: L GGT, L or H AST, L or H ALT)
What are key functional insights related to Creatinine [Male]?
πΉ Marker Description: Kidney filtration test / measure
- not a big hitting marker for kidney function - but look in combination
Creatinine is a waste product of muscle metabolism, excreted by the kidneys.
Produced by breakdown creatinine phsophate in muscles.
muscle mass must be taken into account -
Higher muscle mass = naturally higher creatinine (men typically > women).
24-hour urine collection is a more accurate assessment of kidney function than serum creatinine alone.
higher creatinine, higher Hb and higher Creatinine-Cystatin C ratio = decr risk mortality, cancer,
π» Possible Low Reasons: Diet:
- Malnutrition, low-protein intake, plant-based diets.
Caloric restriction,
- Vitamin D deficiency (affecting muscle & kidney health).
Impaired digestion (low stomach acid, malabsorption issues).
Muscle
- muscle wasting, sarcopenia.
- low muscle mass - eg - Under-exercising (muscle loss reduces creatinine levels).
check lean muscle mass - eg if elderly woman - might not be something to worry about
- overhydration?
- medications?
πΊ Possible High Reasons: Kidney dysfunction (reduced clearance leads to accumulation). = renal insuffienciency, urinary tract congestion, dehydration
Dehydration (affects kidney filtration).
Overexercising (muscle breakdown increases creatinine production).
Excess protein intake or creatine supplementation (supp can remain in bloods for 2-3 weeks post supp - might see in bloods still!)
Benign prostatic hyperplasia (BPH) (growth of prostate) β urinary congestion.
Take into account their muscle mass!!
π Patterns: Conv: 64-104 umol/L / 0.74-1.35 mg/dL
Renal disease: H creatinine, uric acid, phos., LDH , AST
What are key functional insights related to Creatinine [Female]?
πΉ Marker Description: muscle mass must be taken into account - higher the muscle mass = higher the baseline level of creatinine . men typically have higher creatinine than women.
- also need diff level if athletes (high mucle)
24 hour urine collection can give a more accurate assesment of kidney function

- Malnutrition, low-protein intake, plant-based diets.
Caloric restriction,
- Vitamin D deficiency (affecting muscle & kidney health).

πΊ Possible High Reasons: Kidney dysfunction (reduced clearance leads to accumulation). = renal insuffienciency, urinary tract congestion, kidney stones
Dehydration (affects kidney filtration).
Overexercising (muscle breakdown increases creatinine production, recent exertion eg just ran marathon).
Excess protein intake or creatine supplementation.
Medications - eg NSAIDs, antibiotics
Diabetes (incr. blood viscotiy/vol = kidneys have to work harder)
Take into account their muscle mass!!
π Patterns: Conv: 49-90 umol/L / 0.59-1.04 mg/dL
anemia? if kidney markers out of range and low RBC (due to low EPO)
Renal disease: H creatinine, uric acid, phos., LDH , AST
