Scurvy, also called vitamin C deficiency, one of the oldest-known nutritional disorders of humankind, caused by a dietary lack of vitamin C (ascorbic acid), a nutrient found in many fresh fruits and vegetables, particularly the citrus fruits. Vitamin C is important in the formation of collagen (an element of normal tissues), and any deficiency of the vitamin interferes with normal tissue synthesis, a problem that underlies the clinical manifestations of the disorder.

Scurvy in Adults

Even though the number of people suffering from Scurvy has largely come down, poor diet or eating habits can lead to Scurvy. In an adult generally, the symptoms of scurvy include:

Bleeding and swelling of gums
Joint pain, particularly in legs
Weakness or fatigue
Red spots on skin
Swelling in wounds

Scurvy in Infants

Children who suffer from autism spectrum disorder (ASD) are more likely to be affected by scurvy. In infants, there might be different symptoms that could help in detection of the disease, such as:

High fever
Diarrhea
Irritability
Loss of appetite

Diagnosis

If you suspect you have scurvy, your doctor will ask questions about your dietary history, check for signs of the condition, and order a blood test. The blood test will be used to check the levels of vitamin C in your blood serum. Generally, people with scurvy have blood serum levels of vitamin C less than 11 µmol/L.

Treatment

Though the symptoms can be severe, scurvy is fairly simple to treat.

Vitamin C is naturally found in many fruits and vegetables. It’s also often added to juices, cereals, and snack foods. If you suspect you have a mild case of scurvy, eating at least five servings of fruits and vegetables daily is the easiest way to treat the condition.

Oral vitamin C supplements are also widely available and the vitamin is included in most multivitamins. If symptoms continue after a few days of dietary changes, talk with a doctor.

For severe, chronic, cases of scurvy, a doctor may recommend high-doses of oral vitamin C supplements for several weeks to months. There’s no consensus on a specific therapeutic dose for severe scurvy. For these cases, a doctor may recommend high doses of oral vitamin C supplements for several weeks or longer.

Daily Recommended Vitamin C

Daily vitamin C recommendations depend on age, gender, and other health conditions.

Age	Male	Female	During pregnancy	During lactation
0–6 months	40 mg	40 mg
7–12 months	50 mg	50 mg
1–3 years	15 mg	15 mg
4–8 years	25 mg	25 mg
9–13 years	45 mg	45 mg
14–18 years	75 mg	65 mg	80 mg	115 mg
19 + years	90 mg	75 mg	85 mg	120 mg

People who smoke or have digestive conditions typically require at least 35 mg a day more than nonsmokers.

What are the symptoms of scurvy?

Vitamin C plays many different roles in the body. A deficiency in the vitamin causes widespread symptoms.

Typically signs of scurvy begin after at least four weeks of severe, continual vitamin C deficiency. Generally, however, it takes three months or more for symptoms to develop.

Early warning signs

Early warning signs and symptoms of scurvy include:

weakness
unexplained exhaustion
reduced appetite
irritability
aching legs
low-grade fever

Symptoms after one to three months

Common symptoms of untreated scurvy after one to three months include:

anemia, when the blood lacks enough red blood cells or hemoglobin
gingivitis, or red, soft, and tender gums that bleed easily
skin hemorrhages, or bleeding under the skin
bruise-like raised bumps at hair follicles, often on the shins, with central hairs that appear corkscrewed, or twisted, and break easily
large areas of reddish-blue to black bruising, often on the legs and feet
tooth decay
tender, swollen joints
shortness of breath
chest pain
eye dryness, irritation, and hemorrhaging in the whites of the eyes (conjunctiva) or optic nerve
reduced wound healing and immune health
light sensitivity
blurred vision
mood swings, often irritability and depression
gastrointestinal bleeding
headache
