Best Sims 4 Health Mods

Sims 4 health mods come in a variety of forms, each designed to simulate different aspects of physical or emotional well-being. Some focus on physical health, adding illnesses, injuries, checkups, surgeries, and even health insurance systems. Others introduce mental health elements, such as anxiety, depression, or therapy sessions for deeper emotional storytelling.

There are also mods that bring attention to chronic conditions and disabilities, like mobility aids or hearing loss. Other popular wellness mod themes are fitness, nutrition, hygiene, and menstrual health, giving players more control over how their Sim’s bodies react and change.

Below, I’ve put together a list of the best Sims 4 mods covering all aspects, from physical to hygiene and pregnancy-related health conditions.

Healthcare Redux Mod

The Healthcare Redux mod by Adeepindigo is one of the most comprehensive health overhauls available for The Sims 4. This mod introduces a detailed system that covers everything from routine illnesses to emergency medical events. Your Sims can experience symptoms, get diagnosed, receive vaccinations, take prescription medication, and even undergo surgery.

The mod adds new illnesses, injuries, chronic conditions, allergies, and even pregnancy-related complications. Your Sims can face medical emergencies, undergo doctor visits, get immunizations, or manage their health through preventative care, a natural immune system, and various medications or supplements. With the added risk of deadly diseases and a wide range of realistic symptoms, this mod transforms healthcare into an essential and engaging part of everyday gameplay.

The mod also features a menstrual cycle system, dental health, and options for health insurance or wellness plans. Your Sim children and toddlers can get sick, receive pediatric care, or require checkups. If you’re looking to add a realistic layer of medical management to your game, get this mod. It makes sickness more than just a minor moodlet.

The mod is compatible with the base game and Get To Work EP. Please carefully read the installation instructions before adding this to your gameplay.

Private Practice

Private Practice adds an immersive and structured healthcare system to The Sims 4, letting you take your Sim’s medical needs beyond the basic in-game symptoms. This mod introduces features like health checkups, diagnoses, referrals, and chronic conditions such as hypertension and diabetes. Your Sims can sign up for basic insurance, track their BMI and blood pressure, and even schedule specialist appointments through an in-game smartphone app.

They can also get ear infections and seasonal allergies. The mod integrates seamlessly with the base game, offering you a clean UI and regular health reports. If you want more control over your Sim’s well-being without breaking immersion, get this mod. It has an active healthcare management system and realistic consequences for neglect. Note that this mod requires the Get To Work EP to function.

Mental Health Mod

In real life, humans battle with mental health issues and illnesses like depression, gender dysphoria, and eating disorders. Unfortunately, such realism is lacking in the base game, which is why you need Zero’s Mental Health mod.

It’s a thoughtfully built system that brings psychological depth into The Sims 4. With this mod, Sims can develop various mental conditions like anxiety, depression, and PTSD, each with unique symptoms, emotional buffs, and behavioral changes. Your Sim can get diagnosed with 11 possible disorders, which actively affect their moods, autonomy, and social interactions.

Once diagnosed, your Sim can choose therapy and medication options to help manage their mental health. This allows for dynamic recovery and setbacks depending on how you play. This is one of my favorite Sims 4 health mods as it supports storytelling-based gameplay by triggering mental health events after trauma. For instance, if your Sim loses their job, they can become overly anxious about life and their future. I highly recommend getting the mod if you want to represent mental wellness in a nuanced, sensitive, and gameplay-integrated way.

BG Health System

Download: BG Health System

If you’re looking for a base-game compatible Sims 4 health mod, get the BG Health System. It’s designed for players who want a lighter but still immersive medical experience. This mod introduces a simplified system of health events, including common illnesses, injuries, and medication, all without requiring any expansion packs.

Your Sims can get sick, take medicine, and recover over time, with symptoms like coughing, fevers, or fatigue affecting their mood and performance. The mod also includes basic health-related interactions, such as checking temperature or calling in sick to work. If you want medical realism without complexity, the BG Health System is a great choice.

Fitness Controls

Download: Fitness Controls

Fitness Controls by roBurky is one of the best Sims 4 health mods for controlling how your Sim’s body responds to exercise, eating, and lifestyle choices. Instead of drastic and unrealistic body changes after a single workout or indulgent meal, this mod introduces gradual, more realistic weight and muscle gain or loss.

You can fine-tune how fast Sims gain or lose fitness and body fat, making transformations feel more natural over time. I personally use it in my Sim’s fitness journey to reflect real-world pacing. You can learn more information about how this mod works by clicking the link attached.

Purchase Medicine

Download: Purchase Medicine

The Purchase Medicine mod by Andirz enhances a small but crucial part of medical gameplay, which is buying medicine. In the vanilla game, you can only purchase medicine through a computer, and it isn’t always convenient or logical. Luckily, this mod expands your options by allowing Sims to buy medicine from more locations, including refrigerators, medicine cabinets, and even retail shelves if you’re using Get to Work.

This way, your Sim doesn’t have to visit a doctor or go to a hospital to receive healthcare services. They can treat common diseases immediately with medicine. The mod improves immersion and makes treating your sick Sims feel more practical. Note that you can pair the mod with larger medical overhauls like Healthcare Redux or Private Practice.

Dental Care

Download: Dental Care

If you want Sims 4 health mods that introduce a realistic oral hygiene system to the base game, get the Dental Care mod. It expands your Sim’s health routine beyond showers and sleep. With the mod installed, your Sims must brush their teeth regularly to avoid dental issues like cavities, toothaches, or bad breath.

If they neglect their oral hygiene, they will experience visible discomfort, mood debuffs, and even dental emergencies that require professional treatment. Children and toddlers can also develop dental conditions if not properly cared for, making it a great addition for family gameplay.

The mod includes a wide variety of features, such as toothpaste preferences, dental visits, and a reminder system to keep Sims on track. This is one of the most fun and functional Sims 4 health mods to add to your gameplay.

Expanded Pregnancy Interactions

Download: Expanded Pregnancy Interactions

The Expanded Pregnancy Interactions mod adds a much-needed emotional and social layer to pregnancy in The Sims 4. This mod introduces a variety of new interactions and reactions for pregnant Sims and those around them. It makes pregnancies feel like an authentic experience rather than just a countdown to birth.

So, they’ll experience everything from pregnancy complications to pregnancy-related anemia. Sims can share pregnancy news, express concerns, complain about symptoms, or ask others for advice. Partners and family members can also react positively or negatively, depending on traits and relationships. There are also buffs and moodlets tied to morning sickness, cravings, and body image.

If you want to make pregnancy feel more realistic, emotional, and socially dynamic, this mod is a must-have.

Health Life 2.0

Download: Health Life 2.0

If you’re looking for a base game health mod that adds realism to your base game’s health system, get the Health Life 2.0 mod. This in-progress health mod introduces health-related traits, like:

• Anxiety (with panic attacks under stress)
• Bulimia (with food-related whims and negative moodlets)
• Narcolepsy (faster energy decay, coffee cravings)
• Type 2 Diabetes (baking and exercise-based behavior).

Sims can also research relaxation techniques or watch mukbangs on the computer. The creator, JellyPaws, plans to expand the healthcare services menu with traits like ADHD, Depression, PTSD, BPD, Bipolar, and more alongside features like hospital visits, medications, prosthetics, scars, and trait-based interactions.

This mod is designed for storytellers who seek a raw, realistic take on both physical and mental health in their gameplay.

Eye Care

Download: Eye Care

If you’ve ever wished your Sims could visit the eye doctor to get glasses for their vision, Eye Care by Adeepindigo is your best choice. This mod introduces a realistic vision system where your Sims can develop blurry eyesight, get diagnosed with conditions like myopia, and even receive prescription glasses.

Your Sim kids can come home from school with notes about needing an eye exam, while adults might get headaches or eye strain if left untreated. The mod adds vision tests, eye drops, stylish frames, and subtle consequences to make sight feel like a real part of your Sim’s life.

Pregnancy Side Effects

Download: Pregnancy Side Effects

Let’s be honest, pregnancy in The Sims 4 is a little too perfect. Pregnant Sims are always happy and energetic, and they rarely fall sick or experience any side effects, which is quite unusual in real life.

That’s where Lumpinou’s Pregnancy Side Effects mod comes in. Suddenly, your pregnant Sims are dealing with real symptoms like nausea, swollen ankles, mood swings, exhaustion, and even back pain that makes them waddle slower than usual. They’re also experiencing intense cravings, like wanting uncooked carrots or pickles.

This mod affects their energy levels and interactions. You’ll see them need naps more often, snap at loved ones, or groan about how uncomfortable they feel. This is one of the best Sims 4 health mods, and it’s such a game-changer for immersive storytelling.

LittleMsSam’s Pregnancy Overhaul

LittleMsSam’s Pregnancy Overhaul takes the base game’s pregnancy system and completely reworks it into something much more realistic and customizable. The mod changes three aspects:

• Belly Size
• Walkstyle
• Sims who are in the third term can do more

The belly size feature ensures your pregnant Sim doesn’t have an overly huge stomach, while the walkstyle feature disables the default pregnant walking style in the game. Click the link attached to learn more about this Sims 4 mod and how it works.

OBGYN Career

Download: OBGYN Career

If you want to pursue a career in the medical field, try your hand at an OBGYN Career. This custom career lets your Sim become a practicing obstetrician and gynecologist who specializes in reproductive health. They’ll provide care for pregnant Sims before, during, and after childbirth, including routine checkups, prescribing prenatal vitamins, and delivering support.

This career runs on realistic working hours (8 AM to 4 PM, weekdays) and pays $50/hour. The small mod pairs well with other Sims 4 health mods on this list, especially the pregnancy-related ones. If your Sim is starting their medical journey or is already passionate about family health, download this career. It will give them a hands-on, meaningful profession to explore.

Child Birth Mod

Download: Child Birth Mod

The Childbirth Mod by PandaSama is an extensive health mod that completely transforms how labor and delivery work right from the moment your Sim conceives. This mod introduces various concepts such as pregnancy tests, hospital births, home births, pregnancy checkups, midwifery, weaning, lactation, and more.

For instance, instead of the default “hospital rabbit hole,” your Sims can now experience immersive, animated births right at home or in a functional hospital setting. You can choose between natural birth, C-section, or even a water birth with fully animated sequences, midwife support, breathing exercises, and partner involvement.

There are moodlets for contractions, anxiety, and excitement, giving the whole experience an emotional arc. You can also hire a doula, attend early labor appointments, and prepare with a birthing class. If you want pregnancy and delivery to feel deeply personal and realistic, this mod is truly a game-changer. It has everything you need for a fun and interactive pregnancy and childbirth experience.

Wicked Whims – Menstrual Cycle Feature by TURBODRIVER

Download: Menstrual Cycle Feature

Wicked Whims is best known for its adult content, but it also includes a surprisingly detailed and realistic menstrual cycle system. With this feature enabled, Sims who menstruate will go through real-life monthly cycles complete with mood swings, cramps, and bleeding. You’ll need to stock up on pads or tampons, and your Sims can experience discomfort, irritability, or low energy during their period.

The cycle also affects fertility, so you’ll have to pay attention if you’re trying for a baby (or trying not to). This is one of my go-to Sims 4 health mods because it’s fully customizable in the settings. You can adjust length, symptoms, and even fertility tracking based on your gameplay style.

The mod also introduces a Period Tracker app you can use to stay on top of your monthly cycle. This comes in handy when you’re trying to conceive.

Hospital Animation Pack

If you want to make your medical storytelling more realistic and immersive, consider getting the Hospital Animation Pack. This mod includes realistic animations centered around hospital activities. The animations include:

• One featuring a Sim receiving CPR
