You get Lyme Disease when an infected tick plants its chompers into your innocent skin and releases its infection all up in your system. A circular rash forms around the bite, and then a week later, Lyme patients will experience some flu-like symptoms. But if that Lyme goes untreated for very long, it can cause some major neurological complications down the road. The infection can spread to the brain and cause something called Neuropsychiatric Lyme! The symptoms of this late-stage Lyme include tearfulness, depression, anxiety, obsessive compulsion, hallucinations, and even full-blown mania.
Chlamydia is a very popular sexually-transmitted infection (STI) that, among other symptoms, can bring about painful urination and bleeding. It can easily be cleared up with a short stint of antibiotics. However, if left untreated, chlamydia can cause some major complications for both men and women, though they are certainly more serious for the women. Untreated chlamydia can cause something called Pelvic Inflammatory Disorder, which is an inflammation of the uterus, fallopian tubes, and ovaries. PID can also be treated with antibiotics, but if it progresses it can bring about infertility and miscarriages.
Typhoid fever is a bacterial disease transferred by eating or drinking food or water contaminated with the feces of an infected person. Symptoms include a three-week-long fever, diarrhea, and a rash called a rose spot. In the long run, though, typhoid can cause delirium, hallucinations, and paranoia.
Diabetes is a condition when a person's blood has too much sugar (glucose) in it, either because insulin production is insufficient, the body's cells don't react to the insulin, or both. Sufferers of either Type 1 or Type 2 diabetes can experience chronic fatigue, frequent urination, blurred vision, and many more symptoms. Long-term, diabetes can lead to something called diabetic ketoacidosis. This is a rare condition that occurs when the body, unable to break down sugars because of lack of insulin, starts breaking down fats — a process that produces ketones. Diabetic ketoacidosis can lead to frequent urination, abdominal pain, confusion, and even coma.
West Nile Virus is transferred most commonly from infected mosquitoes to humans via bites. Of those who contract it, only 1 out of 5 will suffer symptoms, which can include fever, headache, and other flu-like symptoms. However, West Nile can leave some lingering issues in the blood stream that can really affect a patient's neurological functioning. Serious complications include tremors similar to those people with Parkinson's get, meningitis, and even an inability to think and plan.
Athlete's foot is a fungal infection that affects the feet, and sometimes the hands, and can cause inflammation, itching, stinging, excessive dryness, and crumbly toenails. If left untreated for too long, however, it can cause serious complications (though not at all commonly). For instance, the bacteria in your feet can invade deeper levels of skin (something called cellulitis) and blood poisoning could develop. Not good. Not good.
Hypertension, or high blood pressure, can be brought on by a number of factors, including smoking habits, stress, and a high-sodium diet. It causes a thickening of the arteries, and can lead to heart failure and stroke, among other complications. One that stands out as most debilitating, though, is erectile dysfunction.
Salmonella is a type of food poisoning caused by the Salmonella enterica bacteria. Infection can lead to abdominal cramps, fever, and diarrhea and last for 4 — 7 days. However, in very rare cases Salmonella can actually bring about arthritis in the joints, and even chronic arthritis, which is a real pain (yuck-yuck) to treat.
The same virus that causes chickenpox can come back to haunt you in the form of shingles. If this happens, you could suffer from flu-like symptoms, sensitivity to light, and even an itchy rash. However, if the condition persists for too long, and affects the nerve at the bottom of the brain, it can bring about all kinds of terrible neurological issues. You could get something called Ramsay Hunt syndrome, which can cause a loss of movement of the facial nerves. You wouldn't even be able to say "Oh hell no," because part of your face would be paralyzed!
Impetigo is a bacterial skin infection that usually gets you on the face, arms, or back. It is highly contagious, and will develop blister-like marks that range in size from teeny tiny to quarter-sized. Those marks can crust over, and spread, or the infection can sink to deeper layers of the skin. OR, in 1 percent of cases, a bout of impetigo can leave someone with post-streptococcal glomerulonephritis, which is a super serious kidney disorder. Who wants to be in the 1 percent now?
Rubella, or the German measles, is a viral infection that can cause a rash, itching, and some joint pain. Most children are usually vaccinated against the virus, so it's not a big concern in this day and age. However, if a pregnant woman contracts rubella, it can cause drastic birth defects in the newborn or even be fatal to it. Don't let that happen.
The Norovirus is the leading cause of gastroenteritis, or stomach flu. And stomach flu is synonymous with a whole lot of pooping. Symptoms of gastroenteritis usually only last between 24 and 72 hours, but complications can bring about severe dehydration, which can necessitate a trip to the hospital or can even lead to death.
Another infection that can easily be prevented with a vaccination is mumps. The mild symptoms include fever, fatigue, headache, and loss of appetite. But the long-term complications include deafness and even something called meningoencephalitis, an infection in the brain that can paralyze those stricken with it for life. Just get vaccinated already.
So, we all know what the flu is like, and unless you're super lucky, you've probably had to take a few days off to get better. But, you probably didn't know that having the flu increases your risk of throwing a stroke fourfold! In a recent study, scientists found that flu can dislodge fatty deposits in your arteries which then can move freely around your system and cause a blockage. Holy moly.
