Why Am I Fatigued? What Can I Do About It?
Why
am I fatigued? Many people who see a heart specialist commonly ask this question.
They say they don't have any pep. Everyday they wonder why they feel so weary.
Perhaps their fatigue is new. They used to be able to do things, but now they
always feel worn out.
When I see these patients, often what I find is that
they have a medical illness or frequently even have more than one medical problem.
They may have a blockages of their heart arteries as well as 1-2 other medical
illnesses- diabetes, high blood pressure, or obesity.
A patient who I'll
call Marie illustrates this point. Marie was a 35 year old woman who had come
to see me recently complaining of palpitations. Marie was anxious and fidgety.
I noticed that her lower lip quivered with nervousness. Marie was also overweight.
She was five feet two inches tall and weighed over 230 pounds
"My heart
is jumping out of my chest," she remarked. "I notice it when I do anything
physical such as walking. But it also happens at night when I down to go to bed
and lay on my left side I'll feel it racing."
When I first saw her
I had obtained an EKG in the office. Her EKG showed that she had an abnormal heart
rhythm called a Supra-Ventricular Tachycardia or SVT. An SVT is a rapid beating
of the heart that can be extremely annoying but rarely causes serious complications.
It is sometimes caused by obesity and often by high blood pressure. Marie
suffered from both these conditions.
Because her heart was racing at 120
beats a minute in the office I placed her on a commonly prescribed used medication
called a beta blocker. Beta blockers block the effects of the hormone adrenaline.
They are extremely safe but can cause fatigue.
I ordered a sound wave test
of the heart called an echocardiogram to access her heart function and chamber
size. If the heart is damaged or enlarged it can cause racing. I also had her
get a holter monitor. This is a 24 hour EKG recording.
A month later I saw
Marie back in the office. Marie's echocardiogram showed that her heart's function
was normal
and her chambers were all normal sized. All excellent signs that
her heart rhythm problem wasn't serious. The racing of her heart was gone, but
now she felt exhausted.
"I feel so tired. I can hardly get through
the day and do my work." she complained.
In Marie's case her fatigue
was new, and since I knew that it wasn't heart racing or weakening of hear heart
muscle, it had to be the medication. Indeed, I switched her from a beta blocker
to another type of medication and the fatigue went away.
Although people
often want a quick answer, Discovering why a person feels tired is fairly involved.
First, as a physician we want to make sure nothing serious is happening to the
person.
Because a malfunctioning thyroid gland can be the culprit, one of
the first things to be checked is their thyroid levels. Anemia, low hemoglobin
from bleeding or a variety of sources is also a common cause of fatigue.
Checking
this requires a simple blood count.
Next, for anyone suffering with fatigue
we need to be sure they don't have a systemic illnesses: diabetes, low blood pressure,
excessively high blood pressure, kidney disease can all account for fatigue.
Infections
may also be implicated in fatigue. A routine blood count will measure the white
blood cells picking up any serious infections. A urinalysis is useful for excluding
a urinary infection- a common cause of fatigue if it reaches the blood and causes
what is called sepsis.
Cancer is another grave concern that must be ruled
out when a person complains of fatigue. Excessive weight loss that is not explained,
or any lumps or masses found in the body are tip-offs for cancer. Often a whole
battery of tests will need to be conducted to truly exclude cancer as a reason
for being tired.
Next the medications a person is taking should always be
a examined. Beta blockers, and what are called ace inhibitors can cause tiredness.
In addition, muscle relaxants, anti-anxiety meds, and any medication
that works
to alter the mood may cause fatigue.
Because depression can be a serious
concern for people complaining of tiredness, a thorough questioning to exclude
depression should be undertaken.
So the basic overall approach to fatigue
is first to exclude any medical illness or condition which might on a be causing
tiredness.
If a diligent search has been made and no real medical reason
is found, then the next step is to begin looking a life style habits.
What
we do to our bodies as far as food, exercise, sleep, or the lack of these things
may all be playing a role in feeling sapped of our energy.
The first thing
to examine is a sleep. What is the person's sleep like? Are they getting enough
sleep? If a person is only getting 4-5 hours of sleep a night this could be causing
fatigue. People who work the night shift commonly complain of feeling exhausted.
Next, are they waking a great deal at night, or napping during the day?
Interrupted
sleep can lead to feeling poorly. Sleep apnea is a medical condition in which
sleep is interrupted frequently and commonly leads to lethargy and weariness.
It is also prudent to examine a person's activity level. Regular exercise
has been shown to help with a person's energy level. Is the person walking, bicycling,
swimming- doing some form of aerobic exercise? If you are not
exercising regularly
then consider starting. Exercise also will often be all that it takes to get rid
of fatigue.
Another way to increase the energy is through weight loss.
People who are heavy frequently complain of lacking the will to do much. Just
losing 10-15 pounds can make a tremendous difference in the way a person feels.
You
should also be concerned with your eating habits. People who eat excessive sugar
or soda beverages often complain of fatigue. You'll want to avoid eating simple
sugars if you are having fatigue. Try to avoid excessive intake of carbohydrates
and move towards protein, and vegetable. Certain people tend to feel sluggish
if they
overdo the carbohydrates.
Also you'll want to stay away from
caffeine ingestion. A common complaint of people who use too much caffeine is
lethargy, particularly in the morning.
I know this from personal experience.
I used to feel very tired in the morning. I was drinking 64 oz of caffeinated
diet beverages a day. When I markedly reduced my consumption of caffeinated soda
I had a very good rise in energy.
It may take up to a week to get rid of
the symptoms of fatigue after a person has relinquished caffeine.
Also water
intake is critical. Try to drink a minimum of 1/2 gallon a day provided is alright
with your physician. If you avoid caffeine, and stay away from soda beverages
while drinking plenty of water, you may see a pick up in your energy level.
Our
mental state can also create fatigue. People suffering with depression often complain
that they lack energy. If you have depression, try exercising. Daily exercise
has been shown to combat depression. Worry, anxiety, and
stress also can cause
fatigue. Checking your emotional health will help you discover if this could be
the cause of your low energy level.
Activities that get us more in touch
with our bodies have a particularly helpful effect on our energy level. Try to
spend some time each day doing yoga, gentle stretching, or meditation. These activities
will get you
more in touch with your body, and are helpful for relieving stress
which frequently makes a person tired.
I like the technique called Practicing
Remembrance. This is a skill I teach that combines body awareness with breathing.
It works well for reducing stress and increasing energy.
Something else
that seems to cause fatigue, is eating large meals. People feel better when their
stomach's are empty. Waiting to eat till you are hungry, and pushing away from
the table before you become full can help with the energy level.
Although
may people have never tried it (and you should always consult your physician before
you begin) is to try fasting by drinking only juices for 2-3 days. I have had
a number of people say that they had a significant increase in their energy level
while fasting.
A personal observation that has never been proved scientifically,
is that certain foods can help a person pick up their energy level. Ginseng is
touted as an energy booster, but other foods also seem to work.
A few favorites
of mine are the following:
I sometimes will have people try eating more
lemons. Squeeze 1/2 a lemon in a glass of water with a teaspoon of honey before
bed. Do this for two weeks. Also fenugreek may be helpful. Fenugreek is an Indian
spice that can be found at most health food stores. You can often find it in tea
bags. Place 1-2 tea bags in 1/2 cup of
boiling water and steep for 10 minutes.
Add some honey to counteract the bitterness. Drink twice daily.
Cranberries
can also be useful. Find whole frozen cranberries and unthaw. Blend enough berries
to make 1/3 cup, eat this morning and evening with 1-2 teaspoons of honey (they're
very sour). Don't eat anything for 1 hour after taking the cranberries.
Try
this for 2 weeks.
Camomile can also increase a person's energy level. Tea
bags of camomile are easy to find. Drink 1 cup twice daily on an empty stomach
for 2 weeks.
I hope you find these information about fatigue useful. It
is a problem that can be particularly frustrating. Remember to consult with your
doctor embarking on any of these suggestion.

Heart
tips:
Fish consumption among healthy adults decreases the levels of
inflammatory
markers related to Cardiovascular Disease. A report
from the Journal of the
American College of Cardiology shows that
healthy adults who eat fish just
once a month (compared to people
who don't eat fish at all) have reduced levels
of HsCRP (33%)
and Interleukin-6 (21%): both indicators of inflammation
believed
to be the main culprit in causing heart disease.
