Fame and fortune can make life convenient (or inconvenient), but it does little to protect you from forces that affect all humans, like sickness and disease. It’s true that celebrities usually have the financial means to seek out treatment and comfort when they’re diagnosed, but even they aren’t immune to the sicknesses for which there is no cure.

It might seem like their lives are perfect, but many celebrities are living with illnesses that they hide from the public. Some occurred later in life, while some have been plaguing them since birth. We all know the feeling of wanting privacy and space when we aren’t feeling well, so it must be pretty tough to have to live with a chronic illness while being in the public eye. So how on earth do they do it?

Read about these 15 celebrities who soldier on through sickness and live their dreams like true superstars anyway!

15 Bella, Anwar and Yolanda Hadid: Lyme Disease

The Hadids are just about giving the Kardashians and the Jenners a run for their money when it comes to famous Hollywood families. Mama and Papa Hadid were famous in their own right back in the day, but their three supermodel children, Gigi, Bella, and Anwar, are showing off the Hadid genes to a whole new generation! This family has accomplished so much that you’d never guess that three of them suffer from Lyme disease. Yolanda, Bella, and Anwar are all victims of the bacterial illness that attacks the heart, nervous system, joints, and skin. Yolanda is extremely open about her family’s battle, and constantly posts snaps of what her day-to-day life with Lyme entails. The disease even forced Bella to give up her Olympic dream in 2016. Lyme disease is terrible to live with, but the Hadids prove that you can still have an ultra-successful and happy life after diagnosis.

14 Selena Gomez: Lupus

Selena Gomez revealed to her millions of fans in 2013 that she had been diagnosed with lupus. The autoimmune disease, which occurs more frequently in women than in men, features the body attacking its own cells as if they were foreign invaders. A number of painful symptoms are attached to the disease, including skin rashes, kidney problems, organ inflammation, and mouth ulcers. Typically, women are diagnosed after puberty, when their bodies are ready to give birth to children. The diagnosis forced Selena to cancel her world tour at the time, and step out of the limelight so she could undergo treatment in peace. Unfortunately, there is no cure for lupus, but there are a number of drugs to help manage the symptoms, including corticosteroids and monoclonal antibodies. Selena isn’t alone in her battle with the disease, as her fellow celebrities Seal, Lady Gaga, Toni Braxton, and Nick Cannon also suffer from it.

13 Emilia Clarke: Brain Aneurysm

A brain aneurysm can be fatal. In 2013, the otherwise healthy Emilia Clarke was rushed to the hospital after she suffered a brain aneurysm, or a weak, bulging area in the wall of her artery that supplies blood to her brain. In some cases, this may lead to a stroke caused by blood entering the brain from a rupture. The scariest thing about brain aneurysms is that although they can be very dangerous, they often don’t provide any symptoms until it’s too late. Some symptoms to watch out for include seizures, fainting, nausea, and neck pain, but they won’t always be obvious. HBO didn’t make an official statement after the Game of Thrones star had her brain aneurysm treated just after the third season finished filming. Thankfully, she was able to get right back into filming Season Four after receiving treatment for it and continued her role as our favorite Mother of Dragons!

12 Kim Kardashian: Psoriasis

If you watch Keeping Up with the Kardashians religiously, then you might know that Kim suffers from psoriasis. She was diagnosed with the skin disorder during an episode of the reality show that aired in 2011. But if you don’t watch the show, then you probably had no idea about Kim’s illness: her skin certainly doesn’t look like it’s suffering from anything! Psoriasis is an autoimmune disease which results in a number of skin symptoms, including itchy rashes and red, scaly patches. Though most commonly a skin condition, psoriasis can also inflame other parts of the body and may also harm the health of the heart. While there is no known cure for the condition, it can be managed through a variety of treatments. Kim’s mama Kris Jenner also suffers from psoriasis, which can come about due to stress or certain medications. Smoking and drinking can also cause it to flare up!

11 Miley Cyrus: Tachycardia

Miley Cyrus might be the queen of not giving an eff about anything, and promoting a lifestyle centered around living life to the fullest and having a good time without catering to the opinions of others. Being aware of all of that, she’d be the last person you’d expect to be suffering from a heart condition! Miley’s heart rate actually exceeds the norm, which means she suffers from tachycardia. Her condition doesn’t threaten her life, although some sufferers of tachycardia are prone to cardiac arrest. In the past, Miley has been hospitalized for her illness, as well as having an allergic reaction to antibiotics she was given, and she does think about her condition often. "The type of tachycardia I have isn't dangerous. It won't hurt me, but it does bother me,” she writes candidly in her autobiography. “There is never a time onstage when I'm not thinking about my heart.”

10 Gigi Hadid: Hashimoto’s Disease

Unlike her mom and siblings, Gigi Hadid doesn’t suffer from Lyme. However, she still isn’t exactly the epitome of health, although she definitely seems like it when she kills it on runways and in photoshoots around the world! While she might have escaped her family’s misfortune, she does have another kind of autoimmune disease known as Hashimoto’s disease. This thyroid condition sees the immune cells attacking the thyroid gland, which results in the thyroid struggling to produce hormones. There are a few side effects of Hashimoto’s including heart problems and mood issues. One thing Gigi does have in common with her family is that she doesn’t let her condition slow her down. Instead, she books the top jobs in the industry, works with the biggest names, flies all over the world, and lives the life she wants to live, Hashimoto’s or no Hashimoto’s. If that’s not inspiring, we don’t know what is!

9 Ariana Grande: Severe Allergies

Depending on what you’re allergic to and how severe your allergies are, they can either be a mild bother or totally devastating. Pint-sized songstress Ariana Grande has more than one allergy, and while some of her intolerances are pretty standard, some are more than annoying. Shellfish is a big no-no for her, and the results would be shattering if she did accidentally consume some shrimp. But that’s highly unlikely to happen since she doesn’t eat any seafood, or any other product that comes from an animal due to ethical reasons. Her allergy to bananas would be hard enough if she weren’t a vegan, but since her food choices are kind of limited anyway, being allergic to bananas would suck big time. The most challenging allergy Ariana suffers from, in our opinion, is her allergy to cats. She does seem like more of a dog person, but this is as heartbreaking as life gets, guys.

8 Lena Dunham: Endometriosis

All women can attest to the fact that periods suck. Unfortunately for some women, they are especially painful, irregular, and debilitating. This is known as endometriosis, which has affected actress and writer Lena Dunham for more than 10 years. Before being diagnosed, the star suffered from an extremely irregular cycle, intense pain, and chronic exhaustion every month. The condition is brought about by cells from the uterus lining being displaced and growing in other areas of the body. Not only does endometriosis make life difficult every month, but it can also hinder a woman’s chances of conceiving. Opening up about her struggle in her newsletter in November of 2015, Lena isn’t alone: her fellow stars Susan Sarandon, Jillian Michaels, and Padma Lakshmi also struggle with endometriosis. There are a number of medications available to slow the progression of the disease, and surgery is also available to remove growths from the abdomen.

7 Halle Berry: Type 1 Diabetes

Most fans wouldn’t know it as Halle Berry walks down red carpets in designer gowns and stars in blockbuster hits, but she was born with an illness that is fatal when left untreated. Diabetes mellitus type 1 has affected the actress her whole life, and occurs when the body destroys its own insulin-producing beta cells, located in the pancreas. To control the disease, patients must receive daily doses of insulin from outside sources. In addition to making sure that she gets the insulin she needs every day, Halle puts her health as her top priority in life. She is always careful with her food choices, opting for healthy foods that don’t aggravate her condition, and always leaves room in her schedule for exercise and self-care. It’s this kind of prioritizing that has helped the movie star to balance her amazing career with her health needs, and make sure she doesn’t miss out on anything!

6 Pamela Anderson: Hepatitis C

Hepatitis C is a horrible virus that inflames and scars the liver, resulting in a condition called cirrhosis. While not always a terminal illness, hepatitis C does lead to liver failure and death in around 20% of the people who have it. Actress and model Pamela Anderson became infected with the virus when she used a tattoo needle that had been used by her ex-husband Tommy Lee. Tragically, Pamela has stated that she doesn’t believe she will live for as long as she would have had she not contracted the disease, estimating that she might have another 10 or 15 years left. Her situation is obviously a scary one, but she has managed to keep positive despite her knowledge of the disease, and has mentioned that she still feels good, despite being sick. We think that’s a totally admirable mindset to have, and hope it has a positive effect on her body!

5 Missy Elliot: Graves’ Disease

Missy Elliot is one of the most successful female rappers of all time, having sold over 30 million records in the United States alone during her career that also encompasses record producing, singing, and songwriting. Unbeknown to many, the rap star (real name Melissa Arnette Elliott) suffers from an autoimmune disease called Graves’ disease, or Basedow-Graves disease. The sickness mainly targets the thyroid, and one of the most frequent symptoms is that the thyroid enlarges in size. Missy didn’t reveal until June of 2011 in an interview with People that her illness was the real reason she stepped down from her career. The symptoms prevented her from working because they reached such a severe stage that, for a time, the star couldn’t even hold a pen to write her songs. The incurable thyroid disease is quite rare, and caused the rapper to lose more than 70 pounds after her initial diagnosis.

4 Lil Wayne: Epilepsy

Lil Wayne, whose real name is Dwayne Michael Carter Jr., first drew global attention to his health in 2012. In October of that year, his private plane, which was headed for Los Angeles, had to make an emergency stop in Texas as a result of a medical episode that had occurred mid-flight. It was widely reported that the rapper and label founder had suffered a seizure and required urgent medical attention. After that, more and more stories circulated of Wayne having even more seizures, until he addressed the tabloids in an interview. He confirmed that he does experience seizures because of his neurological condition known as epilepsy. Though debilitating seizures must be difficult to manage along with a busy career, Wayne keeps on top of it like a pro. Another star who suffered from epilepsy was Prince, who had been having seizures since he was a child when he opened up about it in 2009.

3 Catherine Zeta Jones: Bipolar II Disorder

It’s difficult enough to come clean about a physical illness that you’re suffering from as a celebrity, but it can be even tougher to reveal that you’re battling a mental illness, thanks to all the stigma that’s attached to it. Bravely, Catherine Zeta Jones opened up about her diagnosis with bipolar disorder with the intent of removing some of the stigma. In April 2011, the actress checked herself into New Canaan, Connecticut’s Silver Hill Hospital to seek treatment for bipolar II disorder, which is categorized by at least one episode of severe depression and at least one episode of hypomania. Catherine’s husband was diagnosed with throat cancer, which has been discussed much more in the press than Catherine’s own battle. Her mental illness has not stopped her from crafting a fantastic career, and the BAFTA, Screen Actors Guild, and Academy Award-winning actress has currently appeared in more than 30 major movies.

2 Tom Hanks: Type 2 Diabetes

In 2013, Tom Hanks revealed that he has type 2 diabetes on the Late Show with David Letterman. For years, Tom struggled with prediabetes, which is where a person’s blood sugar levels are high, but still not high enough to be classified as diabetes. Since his doctor revealed that his condition progressed to type 2 diabetes, he’s been trying to manage his health with regular exercise and a healthy diet. There are endless risks associated with the disease, which stops the body from effectively controlling its own blood sugar levels. To name a few possible consequences, patients can experience heart disease, nerve damage and even kidney failure if their condition goes untreated. The actor has blamed his own actions for the sickness, claiming that he made the wrong food choices for years and believing that removing the buns from his cheeseburgers would be the only change to his diet required to fix his health.

1 Charlie Sheen: HIV

Once upon a time, being told that you were HIV positive was a death sentence. Though today there are new kinds of medications to help slow the process down and manage the symptoms, it’s still not good news. Actor Charlie Sheen left the world in shock when he announced that he is HIV positive, on Today with Matt Lauer. He had been aware of his condition for four years at that stage, and didn’t want to reveal the truth to the public until he was ready. HIV destroys the T cell in the body, which is a kind of immune system cell. This makes it hard for the body to fight off infections, and when a certain amount of T cells has been destroyed as a result of the virus, a person is classified as having AIDS, or acquired immune deficiency syndrome. There are approximately 1.2 million Americans who are currently living with HIV.
