Reasons You're Always Cold
1/15
Anemia
Wondering why you feel
chilly? This condition might be a cause. Anemia happens when you don't have
enough healthy red blood cells to bring your body all the oxygen it needs. It
will leave you tired, weak, dizzy, and short of breath. It can also make you cold,
especially your hands and feet. Your doctor will find the cause and tell you if
you need changes in your diet, supplements, or another treatment.

Hypothyroidism
It's when the thyroid
gland in your neck doesn't make enough of some hormones. It can make you
overly sensitive to cold. You also may have aching joints, constipation, dry
skin, and weight gain. Symptoms can take years to show up.
Hypothyroidism may be
caused by many things, including illness or treatments for other conditions.
Your doctor can prescribe man-made hormones to replace the ones your body
doesn't make.

Raynaud's Phenomenon
When you have it, blood
vessels in your hands overreact to cold temperatures or stress. During an
attack, which usually lasts from a few minutes to an hour, they narrow and
limit blood supply. This can make your fingers and toes cold and numb, and they
may turn white or blue. As blood returns, they may start to tingle or even
hurt. Medicine can ease symptoms and prevent tissue damage. You may need
surgery if it's a severe case.

Kidney Disease
Diabetes and high blood
pressure often cause kidney disease. Waste may build up to dangerous levels
because your kidneys do a poor job of filtering your blood. This can lower body
temperature and cause other problems. Kidney disease is also linked to anemia,
which can make you feel cold even when it's warm outside. You may get relief
when your doctor treats your kidney disease.

Type 2 Diabetes
If you have this
disease, you may also have anemia and problems with your kidneys and
circulation, which can make you feel cold. Nerve damage from your diabetes can
also leave you chilly. Keeping your blood sugar under control with lifestyle
changes and medicine can help.

Peripheral Artery Disease
It happens when plaque
narrows your arteries and makes it harder for your legs, and sometimes arms, to
get enough blood. If one leg is much colder than the other, especially if it's
also painful, numb, or weak, it could be a sign of the disease. Get emergency
medical help if you notice these symptoms. Changes in diet and exercise can
sometimes help, but your doctor may suggest medicine and sometimes a procedure
or surgery to treat it.

Anorexia Nervosa
It's an eating disorder
that leads you to drastically cut your calorie count and can make you
dangerously thin. The lack of body fat can leave you feeling cold all the time,
especially in the hands and feet. This condition can be life-threatening. Talk
to a doctor if you think you or a loved one has this disorder.
1/15
Flu
It's caused by a virus
that affects your whole body, including your nose, throat, and lungs. You can
get a high fever and chills along with headache, muscle ache, cough, and
weakness. It can be serious, especially for children and older adults. Get an
annual flu vaccine to help stay healthy.
1/15
Peripheral Neuropathy
If your feet feel cold
but aren't cold to the touch, it could be a sign of this condition. It often
starts at the toes and moves up the leg. It happens when an injury or a medical
condition damages your nerves. Diabetes is a common cause. You may also get it
because of infections, liver or kidney disease, you don't get enough vitamins,
or contact with toxic chemicals. Your doctor can treat the cause of the
problem.
1/15
You Don't Get Enough Vitamin B12
It can bring on anemia,
which can make you cold. You can get vitamin B12 when you eat chicken, eggs,
and fish. Some cereals and other foods are fortified with it, too.
Keep in mind that you
may not get enough B12 even if you eat lots of food with it. Some people have
trouble absorbing the vitamin because of an illness or medication they take.
1/15
You Don't Get Enough Iron
Without the right amount
of this nutrient, you can get "iron-deficiency anemia," which can
make you cold. It may be caused by blood loss, a poor diet, or because your
body can't absorb it well. The best source is red meat, but it's also in
poultry, pork, and fish. Some non-meat sources include iron-fortified breads
and cereals, peas, soybeans, chickpeas, and dark green leafy vegetables.
1/15
Hypopituitarism
It happens when your
pituitary gland doesn't make enough of certain hormones. One typical symptom is
that you're sensitive to cold or find it hard to stay warm. You also may get
anemia, lose your appetite, and drop some pounds. Your doctor will try to treat
the cause of your hypopituitarism or suggest medication that replaces the
missing hormones.
1/15
Medication
Some drugs may make you
feel colder as a side effect. Beta-blockers, for example, help the heart relax
and stop your body from making harmful chemicals in response to heart disease.
But you also may feel dizzy, tired, nauseous, and colder in your hands and
feet. Talk to your doctor. He may suggest you switch meds or lower your dose.
1/15
Drinking Alcohol
It may seem to warm you
up at first because it makes your blood flood the widened blood vessels just
under the skin. But your temperature will drop as your body draws blood away
from your core to warm the surface of your skin. Alcohol also depresses the part
of your brain that regulates your temperature. In freezing weather, this can
cause you to get dangerously cold, a condition called hypothermia.
