What Causes Sudden Onset Of Extreme Fatigue

Must Read

Fatigue Is Always A Sign Of A Serious Medical Condition

Fatigue, Causes, Signs and Symptoms, Diagnosis and Treatment.

At some point, nearly everyone suffers from fatigue. In most cases, it’s acute fatigue — fatigue that occurs suddenly but lasts less than three months and is usually caused by lifestyle or environmental factors such as physical exertion, stress, lack of sleep, dehydration, or inadequate diet. In most cases, it’s easily treated by addressing the cause: by reducing stress getting more rest, sleep, or better nutrition or hydrating properly.

Chronic fatigue lasts longer — for more than a few months — and it’s more likely to be associated with an underlying medical condition.

What Is Pots And Why Does It Cause Fatigue

POTS is a group of symptoms resulting from dysfunction of the autonomic nervous system. This branch of the nervous system regulates functions we dont consciously control like sweating and blood circulation.

In people with POTS, more blood collects in the lower body when standing upright. The heart beats faster to pump it up to the brain, but with little success. The causes of POTS are unknown, but the problem is thought to lie in the communication breakdown between the brain and the cardiovascular system.

POTS-related fatigue is physical in nature and the mechanism behind it is not fully understood. It may have several causes, including your body working harder to move the blood.

Preparing For Your Appointment

    • carry out tests to rule out physical causes, such as blood and urine tests.

    Do I Need To See A Doctor

    If you can figure out the reason for feeling tired yourself, and do something about it, then no. If the tiredness is getting in the way of your life, or making you feel unhappy, or you feel unwell, then yes, you should visit your doctor.

    You should definitely see a doctor if you feel tired and have lost weight without trying to. Also see a doctor if you have other symptoms as well as being tired, such as coughing up blood, a change in the way your guts are working, heavy periods or a lump somewhere it shouldn’t be.

    When Should You Worry About Fatigue

    Q.I have been quite fatigued over the past two weeks. How long should I wait before seeing a doctor?

    A. We all go through periods of low energy. Even a week of feeling more tired than usual is not uncommon.

    Yet most people can tell when their fatigue feels like something more serious. If that’s the case, or your fatigue gets worse or lasts longer than a week or two, it’s time to see your doctor. Your fatigue might be related to an underlying illness or infection, especially if it’s accompanied by symptoms, such as a low-grade fever, shortness of breath, or loss of appetite.

    Other reasons to see your doctor about fatigue are if you often wake up exhausted despite sleeping well, do not feel motivated to begin the day, or struggle to do activities that are ordinarily easy. These could be symptoms of a sleep disorder or depression.

    During your exam, your doctor will try to rule out issues like medication side effects. He or she also may order blood tests to determine if the fatigue is related to a specific problem, such as anemia, an underactive thyroid , or liver inflammation . However, don’t be surprised if your doctor does not find a cause. I have found that in most cases people bounce back from fatigue after some rest and a good night’s sleep.

    Does Your Lifestyle Need A Tweak

    First off, ask yourself this: Do you treat your body right?

    “With my patients, I talk about the three pillars of health: sleep, diet, and exercise,” says Theodore Friedman, MD, PhD.

    “If you aren’t getting good sleep, it’s hard to eat well, and it’s hard to exercise. And the same is true the other way around. They’re all related.”

    So try not to short-change yourself on shut-eye. Adults need 7 to 9 hours of sleep. Eat a balanced diet of fruits, veggies, and lean protein, and get a regular dose of physical activity.

    If you’ve checked all those boxes and you still drag through your days, it might be time to check possible medical causes of fatigue.

It is not improved by bed rest and may be worsened by physical or mental activity. Persons with CFS most often function at a substantially lower level of activity than they were capable of before the onset of the illness. CFS is diagnosed two to four times more often in women than in men possibly because of biological, psychological and social influences.
