They don’t warn you until it’s serious.

A cold can cause an unbearable cough or muscle discomfort. On the other hand, much more serious illnesses can go unnoticed for months or even years before they start to manifest.

asymptomatic diseases These are the ones in which the disease or infection does not cause any symptoms, as is the case for many people with COVID-19. If symptoms eventually develop after an asymptomatic period, this phase is called pre-symptomatic. Once symptoms begin, they may be mild and go unnoticed.and makes early diagnosis difficult necessary for better evolution.

Below are some diseases that take time to show their face.

Cancer

Many cancers develop without symptoms in their early stages, meaning they are usually discovered when they are being screened for other reasons or when they are so advanced that they cause health problems.

Pancreatic cancer, one of the deadliest, stands out here. Abdominal pain, weight loss, or jaundice can be an early warning sign of its presence. A persistent cough and chest pain can hide lung cancer. Changes in urine or stool can be associated with colorectal cancer.

Hypertension

So secretive and cautious that he is called “a silent killer”. This is because it is a virtually symptomless chronic condition that can damage vital organs if not detected and managed properly. Without any signs to give it away, hypertension is a leading cause of heart attacks and strokes.

Despite the risks involved, the World Health Organization (WHO) estimates that 46% of adults with hypertension are unaware that they have the condition. In Spain, more than 14 million patients with hypertension, of which 9.5 million are uncontrolled and four are undiagnosed.

This occurs when the blood pressure in the blood vessels is too high (values ​​140/90 mmHg and higher). To detect this, it is necessary to measure the tension.

Sometimes there are signs that may indicate high blood pressure, such as headaches, spontaneous nosebleeds, nervousness, feeling cold, palpitations, or tremors. Being overweight, drinking too much salt or alcohol, not getting enough exercise, or getting older can increase your risk.

Multiple sclerosis

Not only is it a mysterious disease because its cause is unknown, but advance stealthily.

According to the Spanish Society of Neurology, this autoimmune disease, which affects the nervous system (brain and spinal cord), affects 55,000 people in our country. Every year, 1,800 new cases are diagnosed in Spain, 70% in people from 20 to 40 years old.

The type of symptom and its progression will depend on the person, the location of the lesions, and whether it is relapsing multiple sclerosis or one of the progressive forms. It usually begins with vision problems, fatigue, tingling and numbness, dizziness, or pain and spasms. These early signs of multiple sclerosis can now be start 5 years before diagnosisthey emphasize from Spain on multiple sclerosis (EME).

Hepatitis

Hepatitis C is a type of blood-borne virus that causes inflammation and damage to the liver if left untreated. In 30% of cases, infected people clear the virus spontaneously within 6 months, without the need for treatment. In the remaining 70%, the infection becomes chronic, which can cause liver cirrhosis, liver failure and Liver cancer.

According to the WHO, mild viral symptoms such as fatigue and muscle aches may occur during infection. Jaundice (yellowing of the eyes and skin) may sometimes occur. However, most people have no symptoms

and the disease passes without entailing any risk.

The immune system naturally clears the virus in about 3 in 10 people. But for the rest, it becomes a long-term infection. In about 20 yearsMany people learn of their diagnosis because of liver disease.

Today in our country it is believed that those who received Before 1992, it was possible to become infected with hepatitis C through blood transfusions, as it is a high risk factor. In Spain, there are 76,839 people with active hepatitis C virus (HCV) infection in the population attending primary care, of whom 22,478 are undiagnosed. However, updated 2019 estimates show that the prevalence in Spain is 0.15% at the population level, one of the lowest in Europe.

Parkinson’s disease

Around 120,000–150,000 people suffer from Parkinson’s disease in Spain, with around 10,000 new cases diagnosed each year, taking an average of 1 to 3 years to be diagnosed, according to estimates from the Spanish Society of Neurology.

The first symptoms may be mild and go unnoticed. Over time, they worsen and make it difficult for people to function in their daily lives. Typical symptoms include resting tremors, rigidity, or loss of the ability or speed to move. However, a person with Parkinson’s disease may have developed other disorders 5 to 10 years before movement problems appear, such as loss of smell, REM sleep behavior disorder, and depression..

Alzheimer’s disease

According to research, in routine clinical practice, diagnosis is often delayed for several years after the onset of symptoms. These develop slowly and worsen over timeuntil they become so severe that they begin to interfere with daily tasks and cause anxiety.

In the mild stage, after diagnosis, the person continues to be completely autonomous, but notices memory or concentration problems. Which may prompt you to see a doctor. You can start with behavioral changes, disorientation

or problems with a recipe or calculations that were previously performed without problems.

diabetes type 2

Although it sounds trivial and well-known, diabetes is serious chronic disease. This leads to increased glucose levels, which if left unchecked can lead to serious risks. It is the leading cause of blindness, kidney failure, heart attack, stroke and lower limb amputation.

Type 1 diabetes, an autoimmune disease more common in childhood and adolescence, usually comes on quickly and clearly. The same does not happen with type 2 diabetes, which you can live with for years without showing any symptomsThe main causes of this disease are closely related to excess weight and physical inactivity.

Almost 50% of patients with diabetes do not know they have itIn fact, it is for this reason that it is considered a “silent disease” because it raises blood glucose levels, does not cause symptoms in the short term, and when they do occur, it is usually when blood glucose levels are already very imbalanced,” explains Quiron Salud.
