“People Have No Idea”: 70 Medical Issues That Ruin People’s Lives

Invisible illnesses affect around 10% of the 61 million Americans who deal with a physical or mental ailment that limits their movements or senses, according to the Centers for Disease Control and Prevention.

In the US alone, about 1 in 5 adults live with chronic pain, which is actually one of the biggest causes of invisible disability.

Physical issues like endometriosis, autoimmune disorders and long COVID or mental health conditions like anxiety, Post-Traumatic Stress Disorder (PTSD), or Obsessive-Compulsive Disorder (OCD) can all take a toll.

The UK saw a 400% increase in adults seeking an ADHD diagnosis between 2020 and 2023.

Many people with ADHD (Attention-Deficit/Hyperactivity Disorder) also have anxiety, depression, or autism, that can make life unpredictable and exhausting.

Around 10% of women worldwide have endometriosis — a highly painful and invisible condition.

These kinds of medical issues often lead to job barriers, social isolation, and unmet needs.

A lot of people choose to hide their conditions from employers because it might hurt their career prospects or how colleagues treat them.

Research shows that most people hide them so they don’t come across as a liability or a complainer.

They might end up taking on extra work, pushing through symptoms, and pretending to be healthy.

As if these medical issues were not brutal enough, people with serious problems are also facing another obstacle — terms like anxiety or OCD are often used casually now.

People say they’re anxious or have OCD when they’re just stressed or particular about cleanliness, which can make it harder for someone who’s actually struggling to be taken seriously.

“The actual meaning of the term gets diluted and gets associated with simpler and more fleeting experiences. It normalizes illness,” says Dr Zsofia Demjen, a linguist who studies the intersections of language, mind and health.

And when people who are actually suffering hear these terms thrown around for everyday feelings, it can make it harder for them to explain the much deeper struggles their condition actually brings.

Sometimes, even doctors can dismiss serious conditions when a patient’s symptoms don’t follow a tidy textbook narrative.

“Patients are more likely to hear coded phrases like ‘it’s just anxiety,’ ‘your tests are normal,’ or ‘you’re focusing on it too much.’ Over time, these messages land the same way: you can’t trust your own body,” Sarah Fraser, a general practitioner in Nova Scotia, Canada, tells Bored Panda.

“I see this pattern repeatedly in general practice, particularly among patients with chronic, complex, or invisible conditions. Some that come to mind are fibromyalgia, concussions, long COVID or endometriosis,” she adds.

Not speaking up or feeling dismissed can delay treatment and make your health worse.

“Dismissal doesn’t just delay diagnosis — it reshapes how patients see themselves. Many begin to second-guess their pain, apologise for taking up space, or stop seeking care altogether,” says Dr Fraser.

“I’ve had patients tell me the most damaging part wasn’t the illness itself, but being made to feel dramatic, difficult, or delusional for asking for help. It also makes patients not want to even access the healthcare system anymore due to repeated trauma from medical gaslighting.”

It’s hard to empathize when you can’t see someone’s pain or anxiety.

One of the best ways to help someone with a medical condition is simply to listen and offer support without being judgmental.

For patients who feel that their symptoms are dismissed by doctors, being prepared before your appointment can help.

Dr Fraser says: “Writing symptoms down, explaining how they affect daily life, and asking clear, direct questions can shift the dynamic. If something doesn’t sit right, trust that instinct. Good medicine is collaborative, and seeking a second opinion isn’t a failure — it’s an act of self-respect.”
