Gallbladder and Optimal Bile Flow

I have talked a lot over the years about the gallbladder and the role it plays in our overall wellbeing. Recently, however I have been seeing more and more patients come into the office with poor bile flow from a weak gallbladder or some with the gallbladder removed. So this week I am going to revisit this important topic.

Before I do though, I am excited about a book that is set to be released in October called “The Great Remembering”. The science, art and soul of wellness by Ms Cohen, she is the co founder of TED Talks. I am excited as like you I have been feeling that life lately has felt fractured and disconnected. Ms Cohen explores our past, asks better questions, and reminds us that many of the things we’re searching for today—connection, resilience, purpose, healing—may not be new discoveries or ‘hacks’ at all. We simply need to remember and we now have the science to prove it. And that’s what makes this book so powerful. I personally need and want more of this conversation in the world so I thought you might too.

GallBladder and Optimal Bile Flow

What does the Gallbladder actually do?
Let’s dive into what the gallbladder actually does and how to support your digestion, hormones, and terrain for the long haul.
The gallbladder is a small pear-shaped organ that sits just beneath the liver.
Its job is simple — but vital: It stores and concentrates bile. Bile is a bitter, yellow-green fluid made by the liver, and it plays several critical roles:

When bile flows properly, your body works. When it stalls, four critical systems break down simultaneously. This is why bile dysfunction creates the exact pattern of symptoms most women are stuck in — and why no single protocol fixes it.

Main Functions

1. Fat Digestion
   Bile emulsifies fats. No bile = undigested fats, floating stools, deficiency in fat-soluble vitamins (A, D, E, K), and the kind of bloating that gets worse after avocados, oils, and fatty meals.
2. Hormone Clearance
   Metabolized estrogen leaves the body through bile. When bile slows, estrogen recirculates. This is why so many women with “estrogen dominance” actually have a bile flow problem — not an ovary problem.
3. Toxin Removal
   Heavy metals, environmental chemicals, and pharmaceutical residues exit through bile. Sluggish bile = systemic toxin buildup. This shows up as skin issues, brain fog, and unexplained inflammation.
   
4. Microbial Control
   Bile is naturally antimicrobial. It keeps the small intestine sterile. Weak bile is one of the most overlooked drivers of SIBO and Bacterial overgrowth— and the reason SIBO keeps coming back even after antimicrobials.

WHY YOUR BILE SLOWED DOWN

Years of low-fat eating

No fat in the meal = no CCK signal = no gallbladder contraction. Also combined with decades of being told “fat is bad” and choosing ultra processed fats like canola oil trained millions of women’s gallbladders to stop firing. The gallbladder is a muscle. If you stop using it, it weakens. That’s not theory — that’s biology.

Estrogen overload (birth control, HRT, endocrine disruptors)

Synthetic and excess estrogen change bile composition — making it thicker, more cholesterol-saturated, and slower-moving. If you’ve been on birth control for more than a few years, or you’re in perimenopause, this is almost certainly part of your picture.

Thyroid dysfunction

Thyroid hormones directly drive gallbladder motility. Low thyroid = sluggish gallbladder. This is why so many women with Hashimoto’s also have bile issues — and why neither one resolves until both are addressed together.

Missing building blocks (choline, taurine, glycine) Bile is built from these three nutrients. If you’re not eating enough animal protein, organ meats, or egg yolks — your body literally can’t make functional bile. Plant-based diets are particularly vulnerable here, especially long-term.

Chronic stress and high cortisol

Stress diverts blood away from digestion and suppresses vagal nerve tone — the exact signal that triggers bile release. When the nervous system is in sympathetic dominance the digestive system shuts down. When that happens and you eat a fatty meal it can make you feel bloated, gassy and maybe a little nausous, so we tend to avoid fat. Supplements can help support digestion however if you’re continuing eating in fight-or-flight every single day you are not addressing the root cause/s.

Labs that help assess Gallbladder Function

Labs: Here are some of the Labs we look at in office.

GGT — Gamma-glutamyl Transferase MOST OVERLOOKED – Optimal: under 20 U/L (women)

The most sensitive marker of bile flow obstruction and oxidative stress in the liver. Standard reference ranges go up to 50+ — but research consistently shows symptoms and disease risk rising above 20. If yours is “normal” at 35, it’s not normal for your body.

Alkaline Phosphatase (ALP) – Optimal: 70–100 U/L

Elevated ALP can indicate biliary obstruction. Low ALP can indicate zinc deficiency or low bile acid production. Both extremes matter. This test is on every basic panel — make sure your doctor is actually looking at it, not just glancing at “in range.”

Bilirubin (Total + Direct) – Optimal: total 0.4–1.0 mg/dL, direct under 0.3

Elevated direct bilirubin is a flag for bile flow obstruction. Slightly elevated total with normal direct is often Gilbert’s syndrome (genetic, manageable). Both need different protocols — knowing which is which matters.

Cholesterol Panel COUNTERINTUITIVE – Total cholesterol: 160–220 mg/dL

Cholesterol is the raw material for bile acids. If your cholesterol is very low (under 150), you may not have enough substrate to produce adequate bile. This is the OPPOSITE of what most people are taught. Low cholesterol is often a bile production problem, not a heart-protective achievement.

Stool Fat (Steatocrit) RARELY ORDERED

Optimal: minimal to no visible fat

Directly measures fat malabsorption — a clear sign bile isn’t doing its job. Most GIs won’t order it. A functional medicine GI-MAP stool test will. If you have pale, greasy, or floating stools, this is the test that confirms it isn’t in your head.

Estrogen Metabolites (DUTCH) Or GI Map 

Shows how your body is metabolizing and clearing estrogen — which is bile-dependent. Pinpoints whether your hormone symptoms are a production problem, a metabolism problem, or a clearance problem. Most women with estrogen dominance have a clearance problem — and bile is the missing answer.
Here’s how to support your body, step by step:

How to support your healthy bile flow

• Take bile salts (ox bile) with meals containing fat
• Use bitter herbs before meals: dandelion, gentian, artichoke, burdock
• Drink lemon water or diluted apple cider vinegar 15 min before meals
• Supplement phosphatidylcholine or choline to support bile viscosity and flow
• Support cofactors: magnesium, taurine, glycine, molybdenum

Consider adding TUDCA (tauroursodeoxycholic acid), a bile acid that helps thin stagnant bile, protect liver cells, and improve bile flow when the gallbladder is no longer present.
Bile is 95% water — so hydration is critical.

Digestive Enzymes: Use a broad-spectrum enzyme blend with high lipase content and consider HCl support if low stomach acid is suspected. My favorite is Enzymix Pro. We have it on the shelf or you can order through Fullscript.

You are now at higher risk of A, D, E, K deficiency even if you are supplementing. I see this all the time. Use emulsified or micellized versions of vitamins A, D3/K2, and E as they are easier to digest and absorb.

Eat for Healthy Bile Flow

• Eat three balanced meals and do not snack. Let your digestive system rest and recover between meals
• Focus on quality fats, not quantity — avocado, ghee, olive oil, egg yolks
• Avoid fried, processed, and oxidized oils
• Add fiber-rich vegetables to bind excess bile acids and help detox those unwanted pathogens
• Stay well-hydrated throughout the day (filtered water with good quality third-party tested for contaminants mineral salt)
• Avoid ultra processed foods and high sugar content.

Address the Emotional Terrain and the Nervous System

In Chinese medicine, the gallbladder governs:

• Courage, clarity, and decision-making. The ability to “digest life” and move forward boldly. 
• When the organ is not functioning well or has been removed the emotional terrain changes and it can look like – Indecisiveness, Fear of change, Rage or resentment, Difficulty setting boundaries or expressing emotion.

Emotional release work, nervous system healing, breathwork, and somatic therapy are often overlooked and can be deeply supportive

I hope that this information has been helpful and answers some of your questions, adressess concerns and helps provide a path forward. Please share with a friend that could use this info.

Your body is always communicating with you. Symptoms aren’t random—they’re messages. When we understand the root cause, we can work with the body, rather than against it, to restore balance naturally.

Have a healthy week and if your need more support please reach out.
