Diseases is a disturbance in the structure or function of the human, animal, or plant body, and especially in parts of the body that produces certain signs or symptoms or affects a certain location and is not only a direct result of physical injury (britannica.com).

Organisms or body parts that are diseased usually show abnormal signs or symptoms. Thus, the normal condition of an organism or body must be understood in order to recognize the characteristics of the diseases. However, the clear line between the sick and the healthy is not always visible.

The study of disease is called pathology. Pathology studies the determination of the cause (etiology) of disease, understanding of the mechanisms of disease progression (pathogenesis), structural changes associated with the disease process (morphological changes), and the functional consequences of these changes.

Identifying the cause of a diseases appropriately and correctly is needed to carry out treatment appropriately.

Humans, animals and plants are all susceptible to disease. However, what interferes with the normal functioning of one type of organism may not have an effect on another.


Symptomps diseases

infection is a disorder caused by harmful organisms such as viruses, fungi, and bacteria or other parasitic organisms. Many organisms such as bacteria live in our bodies. Usually the bacteria are not harmful or even helpful. But under certain conditions, some of these organisms can become dangerous and can cause disease.

There are several types of diseases that can be transmitted from one person to another through insects or other animals. And you can get sick from eating food or water that is contaminated or exposed to organisms in the environment.

Signs and symptoms of disease vary depending on the organism causing the infection, however, usually if you are exposed to the disease, the body will feel feverish or tired. Mild infections may be resolved by resting and doing home care, while some dangerous infections may require hospitalization.

Many infectious diseases, such as measles and chickenpox, can be prevented by having vaccines. Washing your hands and body frequently can also help protect you from most infectious diseases

Types of Diseases

In the human body, the word disease is often used to refer to conditions that cause pain, dysfunction, distress, social problems, or death for those they suffer from, as well as the same problems for those who come into contact with that person.

In a broad sense, the word diseases often used for injury, disability, disorder, syndrome, infection, isolated symptoms, deviant behavior, and atypical variations of structure and function. While in other contexts and for other purposes the word disease can be considered a distinguishable category. .

Illness can strike people not only physically, but also mentally. Because contracting and living with an illness can change the affected person’s perspective on life.
Death from diseases is called death from natural causes.

There are four main types of disease classifications:

  • Infectious
  • Deficiency
  • Hereditary (including genetic and non-genetic hereditary), and physiological.

The word disease can also be categorized in other ways, such as communicable disease and non-communicable diseases. The deadliest disease in humans are coronary artery disease (blockage of blood flow), cerebrovascular disease and lower respiratory tract infections.

In developed countries, the disease that cause the most disease overall are neuropsychiatric conditions, such as depression and anxiety.

List of Diseases

  1. Cancer
  2. Breast Cancer
  3. Influenza
  4. Heart


According to clevelandclinic.org There are several ways you can prevent disease, such as:

  1. Make healthy food choices
    “For good health and disease prevention, avoid ultra-processed foods and eat homemade meals prepared with basic ingredients,” says Dr. Todorov.

A study published in 2019 concluded that consumption of more than 4 servings of ultra-processed food was associated with a 62% increased hazard for all-cause mortality. For each additional serving, all-caused mortality increased to 18%. These foods can cause chronic inflammation, a normal bodily process gone awry that can contribute to heart disease, diabetes and even cancer.

Ultra-processed food include:

  • Chips.
  • White bread.
  • Donuts.
  • Cookies.
  • Granola or protein bars.
  • Breakfast cereals.
  • Instant oatmeal.
  • Coffee creamers.
  • Soda.
  • Milkshakes.

“It’s crucial to read food labels carefully,” warns Dr. Todorov. “Most foods that come in a package have more than five ingredients or have ingredients that you cannot pronounce. Many foods labeled as diet, healthy, sugar free or fat free can be bad for you.”

What do all healthy diets have in common? They consist of fruits and vegetables, beans, lentils, whole grains like quinoa, brown rice and steel-cut oats, nuts and seeds and healthy oils like extra-virgin olive oil.

“A great example of a healthy eating pattern is the Mediterranean diet,” says Dr. Todorov. “Talk to your doctor or dietitian to help create a meal plan that works for you.”

  1. Get your cholesterol checked
    When checking your cholesterol, your test results will show your cholesterol levels in milligrams per decilitre. It’s crucial to get your cholesterol checked because your doctor will be able to advise you on how to maintain healthy levels, which in turn lowers your chances of getting heart disease and stroke.
  2. Watch your blood pressure
    Do you have high blood pressure? Even if you don’t think so, keep reading. Based on data published from the Centers for Disease Control and Prevention (CDC), about 45% of adults in the United States have hypertension defined as systolic blood pressure, diastolic blood pressure, or are taking medication for hypertension.

Normal blood pressure is defined as blood pressure <120/80 mmHg. Having hypertension puts you at risk for heart disease and stroke, which are leading causes of death in the United States.

Even small weight loss can help manage or prevent high blood pressure in many overweight people, according to the American Heart Association.

“Start off slow and find an activity you enjoy,” says Dr. Todorov. “That can make a big difference in both your blood pressure and health.”

  1. Get up and get moving
    Throw away any common misconceptions about exercising like that it has to be in a gym or a structured environment. Frequency (how often), intensity (how hard) and time (how long) are what matter the most.

“Start where you are and gradually increase your physical activity,” says Dr. Todorov. “My motto is some exercise is good but more is better.”

Taking 10,000 steps a day is a popular goal because research has shown that when combined with other healthy behaviors, it can lead to a decrease in chronic illness like diabetes, metabolic syndromes and heart disease. Exercise does not need to be done in consecutive minutes. You can walk for 30 to 60 minutes once a day or you can do activities two to three times a day in 10 to 20 minute increments.

“There are so many different options for exercise available to us today,” says Dr. Todorov. “Take advantage of free gym and app trials, YouTube videos, resources from your local library and virtual gym classes. Walking in the park adds the benefit of spending time in nature.”

  1. Watch your body mass
    “Dare to be different from the average American, who is more likely to be obese than adults in any other developed nation,” says Dr. Todorov.

To see if you are at a good weight for your height, calculate your body mass index (BMI).

The BMI scale:

Under 18.5: Underweight
18-24.9: Normal

25-29.9: Overweight
30: Obese
If you are overweight or obese, you are at higher risk of developing serious health problems, including heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems and certain cancers. If you are overweight or obese, you doctor or nutritionist will be able to help you get on the right path towards your ideal body mass.

  1. Manage blood sugar levels
    For good preventive health, cut back on soda, candy and sugary desserts, which can cause blood sugar to rise. If you have diabetes, this can damage your heart, kidneys, eyes and nerves over time.

Aside from understanding what makes your blood sugar levels hike up, the American Heart Association recommends eating smart, managing your weight, quitting smoking and moving more as measures to manage your blood sugar.

“In addition, having your blood pressure, blood sugar and cholesterol in a normal range decreases your risk for heart disease,” explains Dr. Todorov. “This lowers your risk of being diagnosed with cancer.”

  1. Quit smoking
    If you smoke, there is probably no other single choice you can make to help your health more than quitting.

The CDC found that smokers are more likely than nonsmokers to develop heart disease, different types of cancer, stroke and more. Not only that, but smoking increases your risk of dying from cancer.

“Smokers lose at least 10 years of life expectancy compared with people who never smoked,” says Dr. Todorov. “People who quit by age 40 reduce their risk of smoking-related death by 90%.”

  1. Get restful sleep
    Sleep restores us and has a huge effect on how we feel. If you have trouble sleeping, try to establish a sleep routine. A good sleep routine includes going to bed and waking up at the same time every day and avoiding eating heavy meals and alcohol. It’s important to stop screen time from your devices 2 hours before bedtime, too.

To wind down before bed, Dr. Todorov recommends:

  • Listen to calming music.
  • Practice mindfulness or meditation.
  • Reflect on the positive moments of the day.
  • Read a book.
  • Have a cup of chamomile tea.
  • Practice 10 minutes of yoga.

“Research shows that daily exercise improves sleep in patients with insomnia, too,” says Dr. Todorov. “Try to avoid vigorous exercise 2 to 3 hours before bedtime.”

  1. Don’t miss health screenings and vaccinations
    It’s no exaggeration: health screenings can save your life. They are designed to catch cancers and serious problems early for more successful treatment.

“There are screening recommendations for adults and women specifically, and varied screenings depending on your family history,” says Dr. Todorov. “Some screening recommendations have changed, so talk to your doctor.”

Making healthy lifestyle changes overnight isn’t realistic, but taking the necessary steps to ensure you’re staying on top of your health will put you ahead and help you be the healthiest you can be.
