Withdrawal method Health Dictionary

A method of CONTRACEPTION which attempts to prevent conception by avoiding intercourse during the fertile part of the menstrual cycle. (See MENSTRUATION; SAFE PERIOD.)... rhythm method

Loss of blood from the UTERUS via the VAGINA occurring when the women’s level of oestrogen hormones (OESTROGENS), PROGESTERONE hormone or PROGESTOGEN drugs falls quickly. The withdrawal bleeding that happens at the end of each month’s cycle of combined oral contraceptive pills (see CONTRACEPTION) imitates the woman’s menstrual period (see MENSTRUATION) but is normally briefer and less in amount.... withdrawal bleeding

Unpleasant physical and mental symptoms that occur when a person stops using a drug or substance on which he or she is dependent (see DEPENDENCE). The symptoms include tremors, sweating, and vomiting which are reversed if further doses are given. Alcohol and hard drugs, such as morphine, heroin, and cocaine, are among the substances that induce dependence, and therefore withdrawal symptoms, when stopped. Amphetamines and nicotine are other examples.... withdrawal symptoms

The process of retreating from society and from relationships with others; usually indicated by aloofness, lack of interest in social activities, preoccupation with one’s own concerns, and difficulty in communicating.

Also called the mucus inspection method, a technique in which a woman notes changes in the characteristics of mucus produced by the cervix in order to predict ovulation for the purposes of contraception or family planning.... billings’ method

A method of contraception, also called the rhythm method, based on abstaining from sexual intercourse around the time of ovulation (calculated by a woman’s menstrual cycles). The method is unreliable because the menstrual cycle may vary (see contraception, natural methods).... calendar method

A form of contraception based on identifying periods for abstinence from intercourse according to the changes in the mucus secreted by a woman’s cervix (see contraception, natural methods of).... cervical mucus method

The use by women of synthetic progestogen drugs, which are often combined with synthetic oestrogens, to prevent pregnancy.

These drugs suppress ovulation and make cervical mucus thick and impenetrable to sperm.

They also cause thinning of the endometrium (lining of the uterus), which reduces the chance of a fertilized egg implanting successfully.

The best-known form of hormonal contraception is the contraceptive pill (see oral contraceptives).

The hormones can also be given as contraceptive implants under the skin, by injection (see contraceptives, injectable), or be released by IUDs.... contraception, hormonal methods of

Methods of avoiding conception based on attempts to pinpoint a woman’s fertile period around the time of ovulation, so that sexual intercourse can be avoided at this time. The calendar method is based on the assumption that ovulation occurs around 14 days before menstruation. Because of its high failure rate, it has been largely superseded by other methods. The temperature method is based on the normal rise of a woman’s body temperature in the second half of the menstrual cycle, after ovulation has occurred. The woman takes her temperature daily using an ovulation thermometer. Sex is considered to be only safe after there has been a sustained temperature rise for at least 3 days.

The cervical mucus method attempts to pinpoint the fertile period by observing and charting the amount and appearance of cervical mucus during the menstrual cycle.

Recognized changes in the mucus occur before and often at ovulation.

The symptothermal method combines the temperature and cervical mucus methods.... contraception, natural methods of

a method of planning pregnancy involving the daily examination of cervical mucus, which varies in consistency and colour throughout the menstrual cycle. Use of a Billings mucus observation chart to help identify the type of mucus enables the woman to have six days’ warning of impending ovulation. [J. and E. Billings (20th century), Australian physicians]... billings method

a technique for expelling the placenta from the uterus. Upward pressure is applied to the uterus through the abdominal wall while holding the umbilical cord taut. When the uterus is elevated in this way, the placenta will be in the cervix or upper vagina and is then expelled by applying pressure below the base of the uterus. [T. Brandt (1819–95), Swedish obstetrician; H. R. Andrews (1872–1942), British gynaecologist]... brandt–andrews method

Unpleasant mental and physical symptoms experienced when a person stops using a drug on which he or she is dependent (see drug dependence). Withdrawal syndrome most commonly occurs in those with alcohol dependence or dependence on opioids, in smokers, and in people addicted to tranquillizers, amfetamines, cocaine, marijuana, and caffeine.

Alcohol withdrawal symptoms start 6–8 hours after cessation of intake and may last up to 7 days. They include trembling of the hands, nausea, vomiting, sweating, cramps, anxiety, and, sometimes, seizures. (See also confusion, delirium tremens, and hallucinations.)

Opioid withdrawal symptoms start after 8–12 hours and may last for 7–10 days. Symptoms include restlessness, sweating, runny eyes and nose, yawning, diarrhoea, vomiting, abdominal cramps, dilated pupils, loss of appetite, irritability, weakness, tremor, and depression.

Withdrawal symptoms from barbiturate drugs and meprobamate start after 12–24 hours, beginning with tremor, anxiety, restlessness, and weakness, sometimes followed by delirium, hallucinations, and, occasionally, seizures. A period of prolonged sleep occurs 3–8 days after onset. Withdrawal from benzodiazepine drugs may begin much more slowly and can be life-threatening.

Withdrawal symptoms from nicotine develop gradually over 24–48 hours and include irritability, concentration problems, frustration, headaches, and anxiety. Discontinuation of cocaine or amfetamines results in extreme tiredness, lethargy, and dizziness. Cocaine withdrawal may also lead to tremor, severe depression, and sweating.

Withdrawal symptoms from marijuana include tremor, nausea, vomiting, diarrhoea, sweating, irritability, and sleep problems. Caffeine withdrawal may lead to tiredness, headaches, and irritability.

Severe withdrawal syndromes require medical treatment.

Symptoms may be suppressed by giving the patient small quantities of the drug he or she had been taking.

More commonly, a substitute drug is given, such as methadone for opioid drugs or diazepam for alcohol.

The dose of the drug is then gradually reduced.... withdrawal syndrome
