Pulmonary Embolism

A pulmonary embolism is a blood clot that gets lodged within one or both lungs. It will block off blood flow and oxygen, putting the person at risk for long-term damage and even possible death. Usually, the cause for this comes from deep vein thrombosis breaking free from a blood clot in the leg. The thing is, a lot of the symptoms of this ordeal seem to mirror those of possible heart problems. Shortness of breath, chest pain, nausea, dizziness, etc. are all heart condition issues too.

Since the blood clot originally begins in the leg, you will likely experience leg pain and swelling well beforehand. This is good for doctors to take a look at alone, so it could save your life to get it checked out before the pulmonary embolism issue even becomes an issue. Without this aid, to begin with, at least 1 in 3 cases of PE are missed. The medical community does need to be better but we can do better as patients by alerting them to things like that leg issue we referenced.

If you ask Dr. Greg House, it is NEVER lupus. This is a running joke in the House television show because lupus has been known to be given as a possible diagnosis for several things. Yet, for some reason, it is missed quite often among those who actually have it. Lupus tends to present like several other autoimmune disorders. Usually, those who have it will have a lot of inflammation in their body that will cause joint pain. The severity differs among all who have it. Lupus can also do damage to the kidneys, lungs, and even the heart. Most who have it will tend to have a butterfly-shaped rash on their face cheeks.

That makes one wonder, with such a sign, how is this one of the most misdiagnosed medical conditions? It is possibly due to not noticing the cheeks, but also assuming it is caused by something else. In a study conducted by the Lupus Foundation of America, roughly 46.5% of people with lupus are misdiagnosed. In their study, they found that over 50% were told that nothing was physically wrong with them, and it was all in their mind. Thus, a possible psychological condition. That is weird to hear too, as x-rays and blood tests could give those doctors a reason to second guess that assumption.

Borderline Personality Disorder

We wish we could tell you an accurate, exact number of those that are currently misdiagnosed yet have this condition. Yet one of the hallmarks of borderline personality disorder is that many do not realize that they have it at all. Many are diagnosed with other mental disorders more often first. Usually, something like bipolar disorder presents in almost the exact same way with a few exceptions. Of course, bipolar disorder mostly affects your mood, causing sometimes wild swings between them. Yet BPD affects how you think and feel about yourself as well as others.

This causes a huge problem that can make one have self-image problems, emotional issues, unstable relationships, and behavioral challenges. Mood issues can make one think bad about themselves too. Both even cause depression and anxiety issues. Thus, it is easy to confuse them. Several studies have been conducted on BPD, but most tend to find that roughly 40% of people were misdiagnosed at some point in their life. However, as high as 10% of the general population are misdiagnosed with BPD when they do not have it.

To be fair to doctors, it is clear that assuming cancer the moment you see a patient is idiotic and terrible for any doctor to think at first. Unless someone has an obvious tumor or something that pops up on a scan, you need a lot of tests to confirm cancer for people. This is why doctors, especially family medicine or urgent care medical professionals, will likely treat the symptoms you’re experiencing. A lot of the issues cancer causes can mask as viruses or bacterial infections.

For example, bladder cancer might present as a standard UTI at first. Yet even if you get past this stage, and see a cancer specialist known as an Oncologist, misdiagnoses happen. According to a 2012 study by the Journal of Clinical Oncology, roughly 44% of the time, these doctors will misdiagnose the type of cancer you might have. Yet normal doctors will rarely think cancer-first like oncologists. They’ll assume a sinus infection rather than brain cancer.
