What is the main cause of hepatitis & What happens if you have hepatitis?

The virus is the most common cause, but auto-immune hepatitis can also occur when the body's immune system attacks and destroys its own kidney cells. Hepatitis is primarily caused by a virus, but there are many other possibilities. A viral infection is the primary cause of hepatitis. And various types of viruses can lead to hepatitis-- some fairly benign, some very serious—such as cytomegalovirus (CMV) and Epstein-Barr virus (EBV).

The main cause of hepatitis is the Hepatitis A virus (HAV). Hepatitis B virus (HBV) and Hepatitis C virus (HCV) can also cause acute hepatitis, but they are responsible for the majority of chronic cases. Chronic hepatic problems may result in the development of cirrhosis or liver cancer, which can be ultimately fatal. It's also possible for an individual to experience co-infection with HAV and HBB/HCV without knowing it since some people infected with HAV do not show any symptoms.

                                  

The human body typically gets rid of the virus in 1-3 months or so without needing any help from drugs or therapies, but about 15% to 40% of people infected with hepatitis A see their symptoms persist for 6 months to 3 years. This can be especially hard on people who are young and otherwise healthy because it often results in interruption of school or work life, not to mention the loss of self-esteem which can damage personal relationships.

Permanently resolving this requires active participation by both doctor and patient; unfortunately, many factors combine to reduce the likelihood that someone will recover completely naturally, including an existing chronic liver disease like cirrhosis (in which case

The main cause of hepatitis is bacteria, viruses, fungi, parasites and chemical substances that damage the liver. The secondary causes may be alcohol abuse or chronic fatty liver disease.

A damaged or diseased liver can lead to alcoholic cirrhosis and other diseases such as spontaneous bacterial peritonitis and encephalopathy.

Hepatitis refers broadly to any inflammatory disorder involving the liver, a diverse organ having many functions in the body. The immune system's response damages hepatocytes - cells that form bile ducts to remove toxins from the blood, produce clotting proteins for blood clots, store energy from food in glycogen so it can be used later when glucose supply from food runs low after starvation occurs.

Some viruses, but more often a drug or toxin that irritates the liver. Drugs and other toxins that can damage the liver include industrial solvents like ammonia, industrial chemicals like benzene, alcohol, acetaminophen (Tylenol), erythromycin (mostly taken to decrease antibiotic resistance), tetracycline antibiotic with surgery concurrent antibiotics), drugs for prevention of malaria such as chloroquine plus proguanil or mefloquine with surgery concurrent clindamycin plus primaquine) and ursodeoxycholic acid.

In adults, viral hepatitis is the most common cause of infectious chronic liver disease, and it's often spread by close contact. In children, foodborne outbreaks are more common. Your body's immune system is a major cause of hepatitis and can be activated by something like a viral infection.

The key to understanding liver disease comes when you realize that the immune system - via T cells and B cells; NK cells; macrophages and natural killer (NK) cells - create inflammation in your gut which ultimately drains into your liver. And when these "Do-or-Die" T lymphocytes or "natural killer" (NK) cell attacks occur it triggers scarring in various regions of your liver which leads to cirrhosis.

The main cause of hepatitis is viral, but it's important to note that there are two types of hepatic viruses that can cause this condition. The first is Hepatitis A (HAV), which comes from fecal matter and is usually spread by food or water contaminated with infected feces. The second type of virus, Hepatitis B (HBV) comes from blood contact, sexual intercourse, or childbirth; however, both types can be transmitted through blood transfusion or drug use (especially needles). According to the Centers for Disease Control and Prevention (CDC), HAV affects about 150 Americans each year; HBV affects roughly 2 million people annually.

The main cause of hepatitis is the virus. But there are other causes including bad hygiene, drinking contaminated water or using dirty injections needles. Furthermore, the hepatitis viruses may spread from an infected mother carrying the disease to her unborn child before it's even born! That can lead to two very different types of hepatitis - one that has a strong reaction where the pregnant woman develops significant liver damage and another that barely affects her at all. And then of course not surprisingly- people who already have chronic health conditions such as diabetes or cirrhosis (liver scarring) and those with weak immune systems due to age or chemotherapy for cancer patients with low white blood cell counts can be more prone to experiencing a chronic infection.

Hepatitis is an inflammation of the liver. It can be caused by either viruses or toxins, including alcohol and prescription medications. Symptoms may include fever, loss of appetite, nausea, vomiting pain in the right side below the ribs when taking deep breaths. The most common type in America is Hepatitis A which you get from sharing food or drinks that are contaminated with tiny amounts of stool from infected people; also known as "gastroenteritis." Getting vaccinated prevents the most acute form usually found in children

Hepatitis is an inflammation of the liver caused by viruses, alcohol, medication. With hepatitis A virus - the symptoms are nausea, vomiting, diarrhea, abdominal pain, and fever. The patient may also have jaundice or low levels of proteins within their blood. Hepatitis B virus - It's usually transmitted through contact with infected blood or other sharps objects such as needles. The symptoms can take up to 6 months before showing signs and it may include dark urine and light-colored stools, joint pain in the lower part of arms and legs (joints hurt worse when pressed) personality changes together with depression phase feelings such as irritability or sadness for no reason at all fatigue along with soreness. If the infection is acute then there may be nausea, vomiting, diarrhea, stomach pain, and jaundice. If chronic then fatigue, loss of appetite, and liver damage may occur.

We recommend immunization for Hepatitis A with the appropriate protection against Hepatitis B with appropriate protection against Hepatitis C with appropriate protection against Herpes Simplex Virus 2 (genital herpes).

Hepatitis is the inflammation of the liver. If you have acute hepatitis, there are often no symptoms associated with it; if you have chronic hepatitis, the most common symptom is fatigue. You can't get Hepatitis from drinking alcohol or eating too much greasy food (unless it's cooked in oil that hasn't been cleaned). You also don't get it by sharing personal items like towels or razors with an infected person.

A person with Hepatitis may feel tired, be pale and lose weight. They may not look sick but can carry the virus that damages their liver. The symptoms of HAV (hepatitis A) last only a few weeks to a couple of months, while symptoms from Hepatitis B can last six months or more; in both cases, there is no specific treatment.

Most people recover fully, and the liver will regain its former function without any need for transplantation or medical intervention in most cases but is often permanently damaged and scarred in others with chronic infections. Hepatitis C sometimes results in severe cirrhosis after decades of infection because it does not cause symptoms until late-stage disease when signs

Hepatitis is an unfortunate and contagious liver disease that we see in at least 500,000 people every year. Hepatitis can be caused by either a virus or a toxin/irritant such as alcohol. Symptoms include jaundice (yellow skin), dark urine, sudden fever that isn't relieved with antibiotics or acetaminophen, abdominal discomfort, and pain that doesn't feel like dysentery - which are hallmarks of the toxic type of hepatitis. Many times, you'll have elevated levels of bilirubin in the blood followed by the destruction of red blood cells due to obstruction of bile ducts if not treated early on.

AI transforming patient care

How Artificial Intelligence Is Transforming Patient Care in India

As a clinician working closely with patients across urban clinics and remote teleconsultation setups, I have seen firsthand how delayed diagnosis, fragmented follow-up, and specialist shortages affect outcomes in India. Artificial intelligence is not a futuristic concept in Indian healthcare anymore. It is actively reshaping how we diagnose diseases, monitor patients, and prevent complications.

AI, when used responsibly under clinical supervision, is becoming a critical support system for doctors and a powerful safety net for patients navigating a complex healthcare ecosystem.


Why India’s Healthcare System Needs AI

India’s healthcare challenges are deeply structural. A large population burdened by lifestyle diseases, combined with uneven access to medical expertise, creates gaps that traditional systems struggle to bridge.

In daily practice, we increasingly see patients presenting late with diabetes, hypertension, heart disease, or cancer. Many ask a simple but important question: why was this not detected earlier? The answer often lies in limited screening, overloaded clinicians, and lack of continuous monitoring.

Chronic conditions dominating Indian clinics today include:

  • Diabetes affecting over 100 million individuals.

  • Hypertension rising even among young adults.

  • Cardiovascular disease driven by late detection.

  • Increasing cancer incidence with delayed diagnosis.

AI matters here because it supports earlier identification of risk patterns, reduces diagnostic delays, and allows clinicians to focus on decision-making rather than data overload.


How AI Is Changing Medical Diagnosis

One common concern patients raise during consultations is whether AI can truly diagnose diseases accurately. In practice, AI does not replace a doctor. It acts as a high-speed analytical assistant.

AI in Imaging and Diagnostics

AI systems can rapidly analyse:

  • X-rays and CT scans.

  • MRI images.

  • Mammograms.

  • Pathology slides.

  • Cardiac and neurological imaging.

These tools flag abnormalities within seconds, allowing doctors to prioritise critical findings. Clinical studies published in peer-reviewed journals have shown that AI models can match specialist-level accuracy for specific imaging tasks when used correctly.

From a physician’s perspective, the real benefit is not speed alone. It is consistency. AI reduces the risk of missed findings during high-volume diagnostic workflows, especially in resource-constrained settings.


Can AI Monitor Patients Outside Hospitals

Patients managing chronic illness often ask whether technology can help them avoid repeated hospital visits. AI-enabled remote monitoring is one of the most meaningful advances in this area.

AI-Supported Remote Patient Monitoring

AI continuously evaluates trends in:

  • Blood pressure.

  • Heart rate variability.

  • Blood glucose patterns.

  • Oxygen saturation.

  • Physical activity and sleep quality.

Rather than reacting to a single abnormal value, AI identifies worsening trends over time. Clinically, this allows early intervention before complications escalate.

Evidence from global health system studies shows that continuous monitoring can significantly reduce avoidable hospital admissions, particularly for diabetes, heart disease, and elderly patients.


Using AI to Predict and Prevent Chronic Diseases

Preventive healthcare remains underdeveloped in India. Most patients seek care after symptoms appear. AI helps shift this model.

By analysing medical history, lifestyle habits, vitals, and environmental factors, predictive models can estimate:

  • Future heart attack risk.

  • Progression of diabetes.

  • Decline in kidney function.

  • Stroke probability.

  • Asthma exacerbation triggers.

Patients often ask if AI can really prevent disease. Prevention here means early warnings. When risk patterns are detected early, doctors can adjust treatment plans, recommend lifestyle changes, and prevent irreversible damage.


Personalised Treatment in a Diverse Indian Population

Indian patients differ widely in genetics, diet, stress patterns, and cultural habits. Standardised treatment protocols often fall short.

AI supports personalised care by analysing:

  • Medication responses.

  • Dietary intake.

  • Blood markers.

  • Sleep and stress trends.

  • Coexisting medical conditions.

For example:

  • In diabetes care, AI helps personalise carbohydrate distribution and medication timing.

  • In hypertension, it identifies sodium sensitivity and stress-related spikes.

  • In hormonal conditions like PCOS, it aligns nutrition and activity with cycle patterns.

From a clinical standpoint, personalised insights improve adherence and reduce relapse rates.


AI-Enabled Telemedicine and Smarter Consultations

Telemedicine has become an essential part of care delivery in India. Patients frequently ask whether online consultations are as effective as in-person visits.

AI enhances telemedicine by:

  • Structuring symptom inputs before consultations.

  • Routing patients to the appropriate specialist.

  • Generating concise medical summaries for doctors.

  • Supporting follow-up reminders and medication adherence checks.

When used correctly, AI reduces diagnostic delays and improves consultation efficiency without compromising safety.


Expanding Healthcare Access Beyond Cities

A major question in public health is whether AI can truly improve rural healthcare access. In practice, it already is.

AI enables:

  • Remote diagnostics supported by portable devices.

  • Virtual specialist consultations for rural clinics.

  • Smartphone-based imaging and screening tools.

  • AI-guided triage in underserved regions.

By reducing dependence on physical proximity to specialists, AI helps bridge longstanding geographical barriers in India’s healthcare system.


Safety, Ethics, and the Role of Doctors in AI Care

Patients rightly express concern about safety, privacy, and over-reliance on technology. These concerns are valid.

Responsible AI use in healthcare requires:

  • Transparent algorithms.

  • Explicit patient consent.

  • High-quality, verified medical datasets.

  • Strict data privacy safeguards.

  • Continuous clinical supervision.

In ethical practice, AI outputs never replace medical judgment. Doctors remain accountable for decisions. Human-in-the-loop verification is essential to ensure patient safety and trust.


What This Transformation Means for Indian Patients

Artificial intelligence is fundamentally changing patient care in India by making healthcare more proactive, more precise, and more accessible. From early diagnosis to personalised treatment and continuous monitoring, AI empowers both patients and clinicians with data-backed clarity.

SecondMedic’s patient-first approach integrates AI as a clinical support system, not a replacement for doctors. By combining medical expertise with digital intelligence, the goal remains simple: better outcomes, earlier intervention, and care that adapts to each patient’s real-world needs.

As clinicians, our responsibility is to ensure that technology serves patients ethically and effectively. When used with care and oversight, AI has the potential to redefine healthcare delivery across India in a way that is inclusive, preventive, and sustainable.
