When we think of the liver, we often think of detoxing, digestion, and maybe the after-effects of a few too many drinks. But what if your immune system started attacking this crucial organ? That’s what happens in Autoimmune Hepatitis (AIH) — a chronic condition where the body’s immune system mistakenly targets the liver, causing inflammation and damage.
If you’re just hearing about this for the first time, or if you’ve been recently diagnosed and are feeling overwhelmed, don’t worry. In this post, we’ll break down what autoimmune hepatitis is, what causes it, how it’s diagnosed, and what living with it looks like.
What Is Autoimmune Hepatitis?
Let’s start with the basics. Autoimmune hepatitis is a chronic liver disease. In simple terms, “autoimmune” means the immune system is misfiring — attacking healthy cells instead of harmful invaders like bacteria or viruses. “Hepatitis” just means inflammation of the liver.
In AIH, the immune system mistakes liver cells for enemies and goes on the offensive, causing ongoing liver inflammation. Left untreated, this can lead to serious complications like cirrhosis (scarring of the liver), liver failure, or even liver cancer.
Who Gets Autoimmune Hepatitis?
While AIH is considered rare, it’s more common than many people think. Here are some key things to know:
- It affects all ages, but is most commonly diagnosed in people between the ages of 15 and 40.
- It’s more common in women — about 70-80% of cases are in females.
- It can occur in people of all ethnic backgrounds.
- It may be associated with other autoimmune disorders, such as Type 1 diabetes, Thyroid Disease, Celiac Disease, etc.
What Causes Autoimmune Hepatitis?
The exact cause? Still a bit of a mystery. But there are some known triggers and risk factors:
- Genetics
Some people may inherit a predisposition for autoimmune diseases. Certain genes, like those in the HLA (human leukocyte antigen) system, have been linked to AIH.
- Environmental Triggers
Environmental factors may act as a trigger for people who are genetically predisposed. These include:
- Viruses (like hepatitis A, B, C, or Epstein-Barr)
- Certain medications
- Exposure to toxins
- Vaccines (very rare and still debated)
- Hormonal changes or stress may also play a role.
Types of Autoimmune Hepatitis
There are two main types of AIH:
Type 1 AIH:
- The most common form.
- It can happen at any age.
- Often associated with other autoimmune diseases.
Type 2 AIH:
- Less common and usually affects children or young adults.
- Tends to be more aggressive.
Both types involve liver inflammation, but they may differ slightly in how they respond to treatment or how quickly they progress.
Symptoms: What Does It Feel Like?
One of the trickiest things about autoimmune hepatitis is that it can be silent for a long time. Some people show no symptoms until the disease is advanced. Others might experience symptoms that are easy to dismiss as “just feeling off.”
Here are the most common signs:
- Fatigue – This is the most common symptom, and it can be severe. For instance, 80 percent of people with AIH experience persistent tiredness, which is not relieved by rest and can hamper daily activities.
- Abdominal discomfort, especially in the upper right side. Studies show that up to 40% of individuals with AIH experience abdominal discomfort, typically in the upper right quadrant where the liver is located.
- Joint pain or muscle aches
- Loss of appetite
- Unexplained weight loss
- Jaundice – yellowing of the skin and eyes
- Dark urine
- Pale stools
- Itchy skin
- Nausea
In more severe cases, especially if cirrhosis has developed, you might also see:
- Swelling in the legs or abdomen
- Mental confusion or difficulty concentrating
- Easy bruising or bleeding
Diagnosing Autoimmune Hepatitis
If a doctor suspects autoimmune hepatitis, they’ll usually start with a combination of blood tests, imaging, and sometimes a liver biopsy.
- Blood Tests
- Liver enzymes (ALT and AST) are usually elevated
- Autoantibodies – these help confirm AIH:
- ANA (antinuclear antibodies)
- SMA (smooth muscle antibodies)
- LKM (liver-kidney microsomal antibodies)
- ANA (antinuclear antibodies)
- Immunoglobulin G (Igg) – typically high
- Liver Function Tests
These measures how well your liver is doing its job — processing waste, producing proteins, etc.
- Liver Biopsy
This is the most definitive test. A small sample of liver tissue is examined under a microscope to confirm the diagnosis and assess the extent of inflammation or damage.
Treatment: What Can Be Done?
The good news? Autoimmune hepatitis is treatable. The goal is to reduce liver inflammation, prevent further damage, and maintain long-term remission.
- Corticosteroids
- Prednisone is usually the first line of treatment.
- It helps suppress the immune system and calm down inflammation.
- However, long-term steroid use can have side effects like weight gain, mood swings, and bone thinning.
When used alone or in combination with azathioprine, it induces clinical, biochemical, and histological improvements in approximately 70–80% of patients.
- Immunosuppressants
- To reduce reliance on steroids, doctors often add azathioprine or mercaptopurine.
- These drugs suppress immune activity and help maintain remission.
- Other Options
- For those who don’t respond to standard treatment or have side effects, alternatives like mycophenolate mofetil, cyclosporine, or tacrolimus may be used.
How Long Is Treatment?
AIH isn’t something that just goes away after a few pills. Treatment is usually lifelong, especially to maintain remission. Some people may eventually be able to taper off medications, but this must be done slowly and under close supervision.
Stopping treatment abruptly can lead to flare-ups, which might cause more liver damage.
Living With Autoimmune Hepatitis
Being diagnosed with a chronic condition like AIH can feel overwhelming. But with the right care, many people go on to live full, healthy lives. Here’s what life might look like:
- Regular Monitoring
You’ll need ongoing blood tests to monitor liver enzymes, check for side effects of medications, and make sure the disease is under control.
- Healthy Diet
There’s no special AIH diet, but eating well supports liver health. Focus on:
- Fresh fruits and vegetables
- Whole grains
- Lean proteins
- Healthy fats (like olive oil or avocado)
Avoid:
- Alcohol (very important!)
- Highly processed foods
- Excessive salt or sugar
- Exercise and Rest
Exercise can help reduce fatigue, while rest is crucial when your body needs to recover. It’s all about balance.
- Mental Health
Chronic illness can take a toll emotionally. Don’t hesitate to seek support through counselling, support groups, or talking with loved ones.
Complications to Watch For
If autoimmune hepatitis isn’t treated, it can lead to serious liver complications:
- Cirrhosis
- Liver failure
- Portal hypertension (high blood pressure in the liver’s blood vessels)
- Liver cancer
In rare cases, if the liver becomes severely damaged, a liver transplant may be the only option.
What’s the Outlook?
With proper treatment, most people with autoimmune hepatitis have a very good prognosis. Early diagnosis and staying on top of your treatment plan make a big difference. For instance, in well-managed cases, the 10-year survival rate is approximately 89% to 96%, with many patients living without the need for a liver transplant.
Some people may experience periods of remission and flare-ups. Others may need consistent medication for life to keep things under control. The key is staying proactive and partnering with a good healthcare team.
Weight Management Is Crucial
Reddit User Amiracle says that the first and most important thing for managing autoimmune hepatitis (AIH) is to monitor your weight. By eating a balanced diet and engaging in regular physical activity, individuals can support their overall health. With proper treatment, AIH is a manageable and treatable condition, so there’s no need to worry as long as you stay proactive in your care.
Living With AIH For 20+ Years
Reddit User Pinelands has been living with AIH for 20 years. They share their life experience, noting that the recurrence rate for those who stop Azathioprine is about 80%, so they plan to take it for life. While opinions on alcohol use vary, they recommend avoiding drinking or consuming very little to protect liver health and prevent the need for a transplant in the future. Despite the social challenges of being a non-drinker, they emphasise that prioritising liver health is more important than succumbing to social pressures.
