Low blood sodium symptons

Hyponatremia is a low sodium level in the blood.[3] It is generally defined as a sodium concentration of less than 135 mmol/L(135 mEq/L), with severe hyponatremia being below 120 mEql/L.[2][7] Symptoms can be absent, mild or severe.[1][8] Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.[2] Severe symptoms include confusion, seizures, and coma.[1][8] Hyponatremia Wikipedia

low blood pressure dangerous only if it causes
noticeable signs and symptoms, such as:
Dizziness or lightheadedness
Fainting (called syncope )
Dehydration and unusual thirst - Dehydration can sometimes
cause blood pressure to drop. However, dehydration does not
automatically signal low blood pressure. Fever, vomiting, severe
diarrhea, overuse of diuretics and strenuous exercise can all lead
to dehydration, a potentially serious condition in which your body
loses more water than you take in. Even mild dehydration ( a loss
of as little as 1 percent to 2 percent of body weight ), can cause
weakness, dizziness and fatigue.
Lack of concentration
Blurred vision
Nausea
Cold, clammy, pale skin
Rapid, shallow breathing
Fatigue
Depression
Low blood pressure can occur with:
Prolonged bed rest
Pregnancy - During the first 24 weeks of pregnancy, it's
common for blood pressure to drop.
Decreases in blood volume - A decrease in blood volume can
also cause blood pressure to drop. A significant loss of blood
from major trauma, dehydration or severe internal bleeding
reduces blood volume, leading to a severe drop in blood pressure.
Certain medications - A number of drugs can cause low blood
pressure, including diuretics and other drugs that treat
hypertension; heart medications such as beta blockers; drugs for
Parkinson's disease; tricyclic antidepressants; erectile dysfunction
drugs, particularly in combination with nitroglycerine; narcotics
and alcohol. Other prescription and over-the-counter drugs may
cause low blood pressure when taken in combination with HBP
medications.
Heart problems - Among the heart conditions that can lead to
low blood pressure are an abnormally low heart rate
(bradycardia ), problems with heart valves , heart attack and heart
failure . Your heart may not be able to circulate enough blood to
meet your body's needs.
Endocrine problems - Such problems include complications with
hormone-producing glands in the body's endocrine systems;
specifically, an under-active thyroid (hypothyroidism), parathyroid
disease, adrenal insufficiency (Addison's disease), low blood
sugar and, in some cases, diabetes.
Severe infection (septic shock) - Septic shock can occur when
bacteria leave the original site of an infection (most often in the
lungs, abdomen or ******* tract) and enter the bloodstream. The
bacteria then produce toxins that affect blood vessels, leading to
a profound and life-threatening decline in blood pressure.
Allergic reaction (anaphylaxis) - Anaphylactic shock is a
sometimes-fatal allergic reaction that can occur in people who are
highly sensitive to drugs such as penicillin, to certain foods such
as peanuts, or to bee or wasp stings. This type of shock is
characterized by breathing problems, hives, itching, a swollen
throat and a sudden, dramatic fall in blood pressure.
Neurally mediated hypotension - Unlike orthostatic
hypotension, this disorder causes blood pressure to drop after
standing for long periods, leading to symptoms such as dizziness,
nausea and fainting. This condition primarily affects young people
and occurs because of a miscommunication between the heart
and the brain.
Nutritional deficiencies - A lack of the essential vitamins B-12
and folic acid can cause anemia, which in turn can lead to low
blood pressure.
Severely low blood pressure can have underlying causes that may:
Be an indication of serious heart, endocrine or neurological
disorders
Deprive the brain and other vital organs of oxygen and
nutrients, ultimately leading to shock, which can be life
threatening

If you've been diagnosed with high blood pressure, you might be worried about taking medication to bring your numbers down.
Lifestyle plays an important role in treating your high blood pressure. If you successfully control your blood pressure with a healthy lifestyle, you might avoid, delay or reduce the need for medication.
Here are 10 lifestyle changes you can make to lower your blood pressure and keep it down.
1. Lose extra pounds and watch your waistlineBlood pressure often increases as weight increases. Being overweight also can cause disrupted breathing while you sleep (sleep apnea), which further raises your blood pressure.
Weight loss is one of the most effective lifestyle changes for controlling blood pressure. Losing just 10 pounds (4.5 kilograms) can help reduce your blood pressure.
Besides shedding pounds, you generally should also keep an eye on your waistline. Carrying too much weight around your waist can put you at greater risk of high blood pressure.
In general:
Men are at risk if their waist measurement is greater than 40 inches (102 centimeters).Women are at risk if their waist measurement is greater than 35 inches (89 centimeters).These numbers vary among ethnic groups. Ask your doctor about a healthy waist measurement for you.
2. Exercise regularlyRegular physical activity - at least 30 minutes most days of the week - can lower your blood pressure by 4 to 9 millimeters of mercury (mm Hg). It's important to be consistent because if you stop exercising, your blood pressure can rise again.
If you have slightly high blood pressure (prehypertension), exercise can help you avoid developing full-blown hypertension. If you already have hypertension, regular physical activity can bring your blood pressure down to safer levels.
The best types of exercise for lowering blood pressure include walking, jogging, cycling, swimming or dancing. Strength training also can help reduce blood pressure. Talk to your doctor about developing an exercise program.
3. Eat a healthy dietEating a diet that is rich in whole grains, fruits, vegetables and low-fat dairy products and skimps on saturated fat and cholesterol can lower your blood pressure by up to 14 mm Hg. This eating plan is known as the Dietary Approaches to Stop Hypertension (DASH) diet.
It isn't easy to change your eating habits, but with these tips, you can adopt a healthy diet:
Keep a food diary. Writing down what you eat, even for just a week, can shed surprising light on your true eating habits. Monitor what you eat, how much, when and why.Consider boosting potassium. Potassium can lessen the effects of sodium on blood pressure. The best source of potassium is food, such as fruits and vegetables, rather than supplements. Talk to your doctor about the potassium level that's best for you.Be a smart shopper. Read food labels when you shop and stick to your healthy-eating plan when you're dining out, too.4. Reduce sodium in your dietEven a small reduction in the sodium in your diet can reduce blood pressure by 2 to 8 mm Hg.
The effect of sodium intake on blood pressure varies among groups of people. In general, limit sodium to less than 2,300 milligrams (mg) a day or less. However, a lower sodium intake - 1,500 mg a day or less - is appropriate for people with greater salt sensitivity, including:
African-AmericansAnyone age 51 or olderAnyone diagnosed with high blood pressure, diabetes or chronic kidney diseaseTo decrease sodium in your diet, consider these tips:
Read food labels. If possible, choose low-sodium alternatives of the foods and beverages you normally buy.Eat fewer processed foods. Only a small amount of sodium occurs naturally in foods. Most sodium is added during processing.Don't add salt. Just 1 level teaspoon of salt has 2,300 mg of sodium. Use herbs or spices to add flavor to your food.Ease into it. If you don't feel you can drastically reduce the sodium in your diet suddenly, cut back gradually. Your palate will adjust over time.5. Limit the amount of alcohol you drinkAlcohol can be both good and bad for your health. In small amounts, it can potentially lower your blood pressure by 2 to 4 mm Hg.
But that protective effect is lost if you drink too much alcohol - generally more than one drink a day for women and for men older than age 65, or more than two a day for men age 65 and younger. One drink equals 12 ounces of beer, five ounces of wine or 1.5 ounces of 80-proof liquor.
Drinking more than moderate amounts of alcohol can actually raise blood pressure by several points. It can also reduce the effectiveness of blood pressure medications.

sodium is a necessary electrolyte, electrolyte imbalance will cause many uncomfortable symptoms... Pounding heart, fatigue, confusion, and a craving for salty foods (if you didn't have that already.)
